Deciphering autoimmune pancreatitis, a great mimicker: case report and review of the literature
Authors: Satya Allaparthi, Mohammed Sageer, Mark J Sterling
Journal: Case Rep Gastrointest Med (2015)

Background. Autoimmune pancreatitis (AIP) is an atypical chronic inflammatory pancreatic disease that appears to involve autoimmune mechanisms. In recent years, AIP has presented as a new clinical entity with its protean pancreaticobiliary and systemic presentations. Its unique pathology and overlap of clinical and radiological features and absence of serological markers foster the disease's unique position. We report a case of diffuse type 1 autoimmune pancreatitis with obstructive jaundice managed with biliary sphincterotomy, stent placement, and corticosteroids. A 50-year-old Caucasian woman presented to our hospital with epigastric pain, nausea, vomiting, and jaundice. Workup showed elevated liver function tests (LFT) suggestive of obstructive jaundice, MRCP done showed diffusely enlarged abnormal appearing pancreas with loss of normal lobulated contours, and IgG4 antibody level was 765 mg/dL. EUS revealed a diffusely hypoechoic and rounded pancreatic parenchyma with distal common bile duct (CBD) stricture and dilated proximal CBD and common hepatic duct (CHD). ERCP showed tight mid to distal CBD stricture that needed dilatation, sphincterotomy, and placement of stent that led to significant improvement in the symptoms and bilirubin level. Based on clinical, radiological, and immunological findings, a definitive diagnosis of AIP was made. Patient was started on prednisone 40 mg/day and she clinically responded in 4 weeks.
Various presentations of the olfactory hallucination in two patients with migraine disease: Case report
Authors: Omeed Partovi, Amir Soheil Tolebeyan
Journal: Front Neurol (2022)
Keywords: phantosmia, headache, migraine, migraine aura, olfactory hallucination
MeSH terms: Case Reports

Objectives:
To report two different presentations of migraine with the olfactory hallucinations. A case with the typical hallucinatory olfactory symptoms preceding migraine headaches and another case with longstanding olfactory hallucinations.
Background:
Migraine prevails in about 12% of the general population, with the migraine aura accountable for at least one-third of these cases. The most common aura is the visual aura, followed by the sensory aura, speech, and motor auras. Olfactory hallucinations preceding the headache phase of migraine are rare. To date, the International Classification of Headache Disorders (ICHD) has not recognized them as a subset of migraine aura.
Results:
This report presents a patient with a typical Phantosmia (PO) aura before her migraine headache and a patient who experiences a longstanding PO aura.
Conclusion:
The olfactory hallucination may present differently in patients with migraine disease. Based on the clinical significance of migraine with olfactory hallucinations, we propose that the ICHD classify this phenomenon as a subtype of aura in the future. However, larger studies are still required to better assess the pathophysiology of this phenomenon.
Odontogenic Cyst with Verrucous Proliferation Exhibiting Melanin Pigmentation
Authors: Nidhi Manaktala, Karen Boaz, Krupa Mehta Soni, Srikant Natarajan, Junaid Ahmed, Keshava Bhat, Nandita Kottieth Pallam, Amitha Juanita Lewis
Journal: Case Rep Pathol (2017)
MeSH terms: Case Reports

Verrucous proliferation arising from odontogenic cysts is a rare entity. We report an unusual case of an infected odontogenic cyst with verrucous proliferation and melanin pigmentation in a 13-year-old male patient who presented with an intraoral swelling in relation to impacted teeth 26 and 27. The enucleated lesion was diagnosed as an odontogenic keratocyst and the patient died within two years of presentation due to multiple recurrences. The clinical, radiological, and microscopic features of the lesion are presented with an attempt to discuss the etiopathogenesis. The case hereby reported is uncommon with only eight cases reported in the literature.
Capillary hemangioma of cauda equina: a case report
Authors: Seyed M Miri, Zohreh Habibi, Mohammad Hashemi, Ali T Meybodi, Seyed Ali F Tabatabai
Journal: Cases J (2009)

Background:
Capillary hemangiomas of spinal nerve root, mostly affecting the cauda equina, are extremely rare.
Case presentation:
A 20-year old man was presented with back pain, radiculopathy, and urogenital symptoms. Magnetic resonance images revealed an intradural extramedullary mass, isointense in T1-weighted and hyperintense in T2-weighted images, with noticeable post injection enhancement. The clinical and radiological findings simulated neurinoma.However, a pinkish lesion was removed surgically and histopathological examination revealed lobules of capillary vessels separated by fibrous tissue, suggesting capillary hemangioma.
Conclusion:
Although rare and sometimes indistinguishable from more common lesion, capillary hemangioma should be in differential diagnosis of any enhancing intradural extramedullary mass at the level of cauda equina or conus medullaris.
Endometriotic Mass After Hysterectomy in a 61 Year Old Post-menopausal Woman: A Case Report and Update
Authors: Marie Pierre Mathey, Jean Bouquet de Jolinière, Attila Major, Francois Pugin, Etienne Monnard, M Fiche, Daniel Sandmeier, Fathi Khomsi, Anis Feki
Journal: Front Surg (2019)
Keywords: endometriosis, hysterectomy, malignant transformation, mullerian adenofibroma, post-menopausal woman
MeSH terms: Case Reports

Endometriosis is a common, hormone-dependent gynecologic disease. Undiagnosed in large proportion of women, managing therapies depend on the impact of quality of life and includes hormonal treatment and pelvic surgery. Less likely endometriosis can occur in post-menopausal women. Malignant transformation of endometriosis is a rare but well-described process, most of time occurring in the ovary, and justifies the practitioner not to underestimate this pathology. We present a case of a 61 year old woman with a symptomatic endometriotic pelvic mass, status post hysterectomy, with no history of endometriosis diagnosed beforehand.
Obsessive-Compulsive Disorder with Suicide Obsessions in a First Responder without Previous Diagnosis of OCD or History of Suicide Attempts
Authors: Vivekananda Rachamallu, Michael M Song, Haiying Liu, Charles L Giles, Terry McMahon
Journal: Case Rep Psychiatry (2017)
MeSH terms: Case Reports

Obsessive-compulsive disorder (OCD) is a distressing and often debilitating disorder characterized by obsessions, compulsions, or both that are time-consuming and cause impairment in social, occupational, or other areas of functioning. There are many published studies reporting higher risk of suicidality in OCD patients, as well as studies describing increased risk of suicidality in OCD patients with other comorbid psychiatric conditions such as major depressive disorder (MDD) and posttraumatic stress disorder (PTSD). Existing case reports on OCD with suicide as the obsessive component describe patients with long standing diagnosis of OCD with suicidal ideations or previous suicide attempts. This report describes the case of a 28-year-old male, who works as a first responder, who presented with new onset symptoms characteristic of MDD and PTSD, with no past history of OCD or suicidality who developed OCD with suicidal obsessions. Differentiating between suicidal ideation in the context of other psychiatric illnesses and suicidal obsessions in OCD is critical to ensuring accurate diagnosis and timely provision of most appropriate treatment. The combination of exposure and response prevention therapy and pharmacotherapy with sertraline and olanzapine was effective in helping the patient manage the anxiety and distress stemming from the patient's OCD with suicidal obsession.

Authors: Justin D Cohen, Robert A Ravinsky, Monis A Khan, Jake Sossamon, Terrence Kim, Kamal Woods, Robert Naruse, Ulrich Batzdorf, J Patrick Johnson
Journal: Cureus (2023)
Keywords: duraplasty, intramedullary spinal cord tumor, progressive postsurgical myelopathy, spinal cord injury, tethered spinal cord
MeSH terms: Case Reports

Progressive post-traumatic postsurgical myelopathy (PPPM) is a known entity that can occur months to years after the initial insult. Symptomatic patients can become myelopathic and have rapid and progressive neurological decline. Surgical correction of PPPM usually involves intradural exploration and lysis of adhesions that carries the risk of further injury to the spinal cord. In this manuscript, we provide a report of a patient presenting more than 50 years after the initial resection of an intramedullary tumor. Additionally, we present and describe a novel surgical technique for managing this difficult problem and restoring normal CSF dynamics.
Pharmacokinetics of anticoagulant edoxaban in overdose in a Japanese patient transported to hospital
Authors: Koichiro Adachi, Jumpei Tuchiya, Satoru Beppu, Kei Nishiyama, Makiko Shimizu, Hiroshi Yamazaki
Journal: J Pharm Health Care Sci (2020)
Keywords: anticoagulants, overdose, pharmacokinetic modeling
MeSH terms: Case Reports

Background:
The anticoagulant edoxaban is used clinically at doses of 30-60 mg/day; however, we experienced a patient who had taken an overdose of edoxaban of 750 mg. We investigated the pharmacokinetics of edoxaban in this patient by using liquid chromatography-tandem spectrometry to estimate the follow-up period in emergency clinical practice with this medicine.
Case presentation:
The patient was a 57-year-old woman (body weight, 69 kg) who had taken a single oral dose of 750 mg of edoxaban in a suicide attempt. She was emergently admitted to Kyoto Medical Center. The patient's edoxaban plasma concentrations during ambulance transport (8 h after oral administration) were ~ 4900 ng/ml, and the concentration gradually decreased to ~ 10 ng/mL and to detectable but unmeasurable levels of ~ 1.0 ng/mL at 60 h and 100 h, respectively. The linear range of the relationship between the dose and plasma concentration was assumed to have been exceeded during the first 8 h; however, the measured elimination rate of edoxaban was similar to that visualized curves predicted by a simplified physiologically based pharmacokinetic model previously established.
Conclusion:
Simplified physiologically based pharmacokinetic models for creating visualized curves have proven to be useful not only during drug discovery or chemical risk assessment but also in cases of medical poisoning. We used a physiologically based pharmacokinetic model previously established for edoxaban to predict the pharmacokinetics in the current case. It is hoped that the results of this study, which encompass drug monitoring data in the patient and visualized pharmacokinetic prediction, will serve as an index when setting the treatment and follow-up period in cases of drug overdose for medicines such as edoxaban in emergency clinical practice.
Testicular Inflammatory Myofibroblastic Tumor: A Known Entity at a Very Rare Site
Authors: Hans-Ullrich Voelker, Daniel Kuehn, Annette Strehl, Stefan Kircher
Journal: Case Rep Urol (2017)
MeSH terms: Case Reports

Inflammatory myofibroblastic tumors (IMT) are distinctive lesions of unknown etiology, composed of myofibroblastic spindle cells with an associated inflammatory background. They can occur in a wide age range and at all anatomic sites, but most frequently they can be observed in the lung (especially in pediatric cases), abdomen, or retroperitoneum. The urinary bladder is one of the most common sites in urological cases. We present a very rare case of IMT of the testis. Clinically, a 40-year-old patient showed a palpable painless lesion of the right testis. Ultrasound examination showed two solid intratesticular foci. During surgical intervention, the intraoperative frozen section revealed mesenchymal tumors admixed with an uncommon inflammatory infiltrate, consistent with a reorganized abscess. Despite the benign result, orchiectomy was performed due to the multifocal presentation and the large size of 3 cm. The final diagnosis was IMT without ALK-rearrangement. Incomplete resection increases the risk of local relapses to 30%. In this case, a complete resection could be achieved and the patient is free of tumor 15 months later.
Successful Obliteration of a Pseudoaneurysm from Post-CEA Repair Secondary to a Pruitt-Inahara Shunt Using a Stent Graft
Authors: Vishal Dahya, Prasad Chalasani
Journal: Case Rep Vasc Med (2013)

Pseudoaneurysms of the carotid artery are very uncommon complications following carotid endarterectomy. Pseudoaneurysms are usually caused by any kind of blunt injury or trauma during carotid artery surgery. CEA has become an increasingly more common vascular surgery performed in the United States. The standard of treatment for a carotid PA has been open surgical repair with excision of the defect and then a graft reconstruction of the artery. Advancements in endovascular intervention have helped to make it a more popular choice in treatment because of the positive results and less invasive approach. This case report describes the successful obliteration of a large post-CEA PA using a stent graft. The PA was likely secondary to the use of a Pruitt-lnahara Shunt because it was found to be distal to the endarterectomized area of the carotid artery which means that the defect was likely caused by the balloon portion of the shunt. This case demonstrates the feasibility of using endovascular interventional techniques to treat a PA using a stent graft.
Prenatal and postnatal diagnosis of Phelan-McDermid syndrome: A report of 21 cases from a medical center and review of the literature
Authors: Ying Hao, Yang Liu, Jingxin Yang, Xingping Li, Fuwei Luo, Qian Geng, Suli Li, Peining Li, Weiqing Wu, Jiansheng Xie
Journal: Front Genet (2022)
Keywords: 22q133 deletion syndrome, phelan–mcdermid syndrome (pms), shank3 gene, genotype–phenotype correlations, prenatal diagnosis

Background: Phelan-McDermid syndrome (PMS), caused by deletions at 22q13.3 and pathogenic variants in the SHANK3 gene, is a rare developmental disorder characterized by hypotonia, developmental delay (DD), intellectual disability (ID), autism spectrum disorder (ASD), dysmorphic features, absence of or delayed language, and other features. Methods: Conventional karyotyping, chromosomal microarray analysis (CMA), and whole exome sequencing (WES) have been used to detect genetic defects causing PMS. We summarized the genetic and clinical findings from prenatal to postnatal stages of detected cases of PMS and mapped potential candidate haploinsufficient genes for deletions of 22q13. This study aimed to summarize the laboratory findings, genetic defects, and genotype-phenotype correlations for Chinese patients with PMS. Results: Seven prenatal cases and fourteen postnatal cases were diagnosed with PMS in our center. Thirteen cases had a deletion ranging in size from 69 to 9.06 Mb at 22q13.2-q13.33, and five cases had a pathogenic variant or an intragenic deletion in the SHANK3 gene. Three familial cases with a parental carrier of a balanced translocation were noted. A review of the literature noted another case series of 29 cases and a report of five cases of PMS in China. Genotype-phenotype correlations confirmed haploinsufficiency of the SHANK3 gene for PMS and suggested other candidate haploinsufficient genes TNFRSFI3C and NFAM1 genes for immunological features and TCF20, SULT4A1, PARVB, SCO2, and UPK3A genes for intellectual impairment and behavioral abnormality, neurological features, macrocephaly/hypotonia, oculopathy, and renal adysplasia, respectively. Conclusion: Indications for prenatal diagnosis of PMS are not specific, and approximately 85% prenatally diagnosed PMS elected termination of pregnancies after genetic counseling. For postnatal cases, 62.5% were caused by a deletion at 22q13 and 37.5% were caused by a pathogenic variant or an intragenic deletion in the SHANK3 gene. Approximately 6.7% of cases with a deletion were familial, and almost all pathogenic variants were de novo. Combined karyotype, CMA, and WES should be performed to increase the diagnostic yield. The identification of other candidate haploinsufficient genes in deletions of 22q13.2-q13.33 could relate to more severe dysmorphic features, neurologic defects, and immune deficiency. These results provided evidence for diagnostic interpretation, genetic counseling, and clinical management for the Chinese cases of PMS.

Authors: Annalisa Vetro, Sara Pagani, Margherita Silengo, Mariasavina Severino, Elena Bozzola, Cristina Meazza, Orsetta Zuffardi, Mauro Bozzola
Journal: Mol Cytogenet (2014)
Keywords: 2p duplication, 2q deletion, growth hormone deficiency, pituitary hypoplasia
MeSH terms: Case Reports

We report on a male child ascertained at 4.8 years of age with severe growth failure, growth hormone (GH) deficiency, psychomotor delay with prevalent speech impairment, and a distinct phenotype. An evaluation of his hypothalamic-pituitary region by Magnetic Resonance Imaging (MRI) revealed pituitary hypoplasia with pituitary stalk interruption and ectopic posterior pituitary lobe, which are considered prognostic markers of permanent GH deficiency. Prenatal chromosome analysis because of increased nuchal translucency revealed a normal male karyotype, whereas postnatal high resolution banding raised the suspicion of a 2q abnormality. Subsequently, array Comparative Genomic Hybridization (array-CGH) revealed a de novo complex genomic rearrangement consisting of a 2p25 duplication and a 2q37 deletion: arr[hg19] 2p25.3p25.1(30,341-9,588,369)x3,2q37.2q37.3(235,744,424-243,041,305)x1. FISH analysis showed that the abnormal chromosome 2 mimicked the derivative of an inversion with the duplicated 2p region located distally at 2q. This is, to the best of our knowledge, the first case with distal 2p25 duplication and 2q37 deletion and pituitary malformation leading to GH deficiency.
Bilateral compartment syndrome of the lower limbs after urological surgery in the lithotomy position: a clinical case
Authors: José Maciel Caldas Dos Reis, Lauro José Mendes Queiroz, Pablo Ferreira Mello, Renan Kleber Costa Teixeira, Fábio de Azevedo Gonçalves
Journal: J Vasc Bras (2019)
Keywords: compartment syndromes, fasciotomy, postoperative complications
MeSH terms: Case Reports

Acute compartment syndrome of the lower extremities after urological surgery in the lithotomy position is a rare but potentially devastating clinical and medicolegal problem. We report the case of a 67-year-old male who underwent laparoscopic prostatectomy surgery to treat cancer, spending 180 minutes in surgery. Postoperatively, the patient developed acute compartment syndrome of both legs, needing emergency bilateral four-compartment fasciotomies, with repeated returns to the operating room for second-look procedures. The patient also exhibited delayed wound closure. He regained full function within 6 months, returning to unimpaired baseline activity levels. This report aims to highlight the importance of preoperative awareness of this severe complication which, in conjunction with early recognition and immediate surgical management, may mitigate long-term adverse sequelae and improve postoperative outcomes.
Myofunctional Treatment of Anterior Crossbite in a Growing Patient
Authors: Marianna Pellegrino, Maria Laura Cuzzocrea, Walter Rao, Gioacchino Pellegrino, Sergio Paduano
Journal: Case Rep Dent (2020)
MeSH terms: Case Reports

The purpose of this case report is to add another means of treatment for the anterior crossbite malocclusion in early mixed dentition. The selected functional device is an eruption guidance appliance (EGA). The analysed patient had a functional anterior crossbite, a mandibular protrusion tendency, and a normodivergent growth pattern. The early treatment was suggested to correct the malocclusion and avoid unfavourable occlusal conditions that could end in a class III malocclusion growth pattern. After 18 months of treatment, with night-time use, the malocclusion was completely resolved. This therapy strategy allowed the correction of the sagittal jaws' relationship and maximum control of the vertical dimension. After 2 years of follow-up, the results were preserved. The peculiarity of this kind of intraoral orthodontic tools is the use of the erupting forces rather than the active forces. This early treatment of anterior crossbites with EGA may be considered an effective treatment approach for achieving good functional and aesthetic results.
Tuberculum sellae meningioma with possible tacrolimus neurotoxicity manifesting as manic-like psychosis after kidney transplantation
Authors: Eun Hyun Seo, Seung-Gon Kim, Yong Soo Cho, Hyung-Jun Yoon
Journal: Ann Gen Psychiatry (2019)
Keywords: immunosuppressant, kidney transplantation, meningioma, neurotoxicity
MeSH terms: Case Reports

Background:
Although kidney transplantation is the best treatment option for chronic kidney disease, the accompanying immunosuppressive treatment can induce severe neurotoxicity presenting, on rare occasions, as psychosis. However, a brain tumor synchronous with immunosuppressant neurotoxicity has never been reported in a kidney transplant recipient. Herein, we report the first case of possible tacrolimus neurotoxicity with a meningioma manifesting as manic-like psychosis after kidney transplantation.
Case presentation:
A 63-year-old male presenting with acute psychotic mania was admitted to a psychiatric ward approximately 2 years after kidney transplantation. On brain magnetic resonance imaging, a tuberculum sellae meningioma was found, and hyperintense white matter lesions with possible tacrolimus-induced neurotoxicity were seen on fluid-attenuated inversion recovery images. Interestingly, the patient showed no visual field defects, and his blood tacrolimus concentration was within therapeutic ranges. After 3 weeks of adjunctive treatment with blonanserin, most of the symptoms had abated.
Conclusions:
The present case highlights the fact that neuroimaging studies are necessary to investigate underlying causes, as well as immunosuppressant neurotoxicity, which should all be considered when atypical psychiatric symptoms develop after organ transplantation. Further, this case suggests that the additional use of atypical antipsychotics while maintaining immunosuppressants may be effective for manic-like psychotic symptoms secondary to possible immunosuppressant neurotoxicity synchronous with a meningioma.
Second Cancers in a Patient with Gastric MALT Lymphoma
Authors: Lucy Navsaria, Alfonso Badillo, Michael Wang
Journal: Case Rep Med (2020)
MeSH terms: Case Reports

Mucosa-associated lymphoid tissue (MALT) lymphoma is an extranodal low-grade B-cell lymphoma, which is thought to arise from a background of chronic immune stimulation, bacterial, viral, or autoimmune stimuli. Treatment advances have increased the number of MALT lymphoma survivors, but there is still debate as to whether these patients are at a higher risk of developing second cancers. This is a case of a long-surviving (>20 years) patient with multiple diagnosed malignancies following MALT lymphoma. We describe how modern oncological treatment plans can provide patients with prolonged survival and increased quality of life despite increasing age and multiple malignancies.
