Medical specialty:  Radiology
 MRI of the Cervical, Thoracic, and Lumbar Spine

INTERPRETATION: , MRI of the cervical spine without contrast showed normal vertebral body height and alignment with normal cervical cord signal.  At C4-C5, there were minimal uncovertebral osteophytes with mild associated right foraminal compromise.  At C5-C6, there were minimal diffuse disc bulge and uncovertebral osteophytes with indentation of the anterior thecal sac, but no cord deformity or foraminal compromise.  At C6-C7, there was a central disc herniation resulting in mild deformity of the anterior aspect of the cord with patent neuroforamina.  MRI of the thoracic spine showed normal vertebral body height and alignment.  There was evidence of disc generation, especially anteriorly at the T5-T6 level.  There was no significant central canal or foraminal compromise.  Thoracic cord normal in signal morphology.  MRI of the lumbar spine showed normal vertebral body height and alignment.  There is disc desiccation at L4-L5 and L5-S1 with no significant central canal or foraminal stenosis at L1-L2, L2-L3, and L3-L4.  There was a right paracentral disc protrusion at L4-L5 narrowing of the right lateral recess.  The transversing nerve root on the right was impinged at that level.  The right foramen was mildly compromised.  There was also a central disc protrusion seen at the L5-S1 level resulting in indentation of the anterior thecal sac and minimal bilateral foraminal compromise.,IMPRESSION: , Overall impression was mild degenerative changes present in the cervical, thoracic, and lumbar spine without high-grade central canal or foraminal narrowing.  There was narrowing of the right lateral recess at L4-L5 level and associated impingement of the transversing nerve root at that level by a disc protrusion.  This was also seen on a prior study.,

MRI L-Spine - Subarachnoid Seeding 
Medical specialty:  Radiology
 MRI L-spine - History of progressive lower extremity weakness, right frontal glioblastoma with lumbar subarachnoid seeding.

CC:, Progressive lower extremity weakness.,HX: ,This 52y/o RHF had a h/o right frontal glioblastoma multiforme (GBM) diagnosed by brain biopsy/partial resection, on 1/15/1991. She had been healthy until 1/6/91, when she experienced a generalized tonic-clonic type seizure during the night. She subsequently underwent an MRI brain scan and was found to have a right frontal enhancing lesion in the mesial aspect of the right frontal lobe at approximately the level of the coronal suture. There was minimal associated edema and no mass effect. Following extirpation of the tumor mass, she underwent radioactive Iodine implantation and 6020cGy radiation therapy in 35 fractions. In 11/91 she received BCNU and Procarbazine chemotherapy protocols. This was followed by four courses of 5FU/Carboplatin (3/92, 6/92, 9/92 ,10/92) chemotherapy.,On 10/12/92 she presented for her 4th course of 5FU/Carboplatin and complained of non-radiating dull low back pain, and proximal lower extremity weakness, but was still able to ambulate. She denied any bowel/bladder difficulty.,PMH: ,s/p oral surgery for wisdom tooth extraction.,FHX/SHX: ,1-2 ppd cigarettes. rare ETOH use. Father died of renal CA.,MEDS: ,Decadron 12mg/day.,EXAM: ,Vitals unremarkable.,MS: Unremarkable.,Motor: 5/5 BUE, LE: 4+/5- prox, 5/5 distal to hips. Normal tone and muscle bulk.,Sensory: No deficits appreciated.,Coord: Unremarkable.,Station: No mention in record of being tested.,Gait: Mild difficulty climbing stairs.,Reflexes: 1+/1+ throughout and symmetric. Plantar responses were down-going bilaterally.,INITIAL IMPRESSION:, Steroid myopathy. Though there was enough of a suspicion of "drop" metastasis that an MRI of the L-spine was obtained.,COURSE:, The MRI L-spine revealed fine linear enhancement along the dorsal aspect of the conus medullaris, suggestive of subarachnoid seeding of tumor. No focal mass or cord compression was visualized. CSF examination revealed: 19RBC, 22WBC, 17 Lymphocytes, and 5 histiocytes, Glucose 56, Protein 150. Cytology (negative). The patient was discharged home on 10/17/92, but experienced worsening back pain and lower extremity weakness and became predominantly wheelchair bound within 4 months. She was last seen on 3/3/93 and showed signs of worsening weakness (left hemiplegia: R > L) as her tumor grew and spread. She then entered a hospice.
MRI Orbit/Face/Neck 
Medical specialty:  Radiology
 MRI Orbit/Face/Neck with MR Angiography of the Head - An infant with facial mass

EXAM: , MRI orbit/face/neck with and without contrast; MR angiography of the head,CLINICAL HISTORY: , 1-day-old female with facial mass.,TECHNIQUE:,1.  Multisequence, multiplanar images of the orbits/face/neck were obtained with and without contrast.  0.5 ml Magnevist was used as the intravenous contrast agent.,2.  MR angiography of the head was obtained using a time-of-flight technique.,3.  The patient was under general anesthesia during the exam.,FINDINGS:,  MRI orbits/face/neck:  There is a pedunculated mass measuring 5.7 x 4.4 x 6.7 cm arising from the patient's lip on the right side.  The mass demonstrates a heterogeneous signal.  There is also heterogeneous enhancement which may relate to a high vascular tumor given the small amount of contrast for the exam.  The origin of the mass from the upper lip demonstrates intact soft tissue planes.,Limited evaluation of the head demonstrates normal appearing midline structures.  Incidental note is made of a small arachnoid cyst within the anterior left middle cranial fossa.  The mastoid air cells on the right are opacified; while the left demonstrates appropriate aeration.,MR angiography of the head:  Angiography is limited such that the vessel feeding the mass cannot be identified with certainty.  The right external carotid artery is noted to be asymmetrically larger than the left, the phenomenon likely related to provision of feeding vessels to the mass.  There is no carotid stenosis.,IMPRESSION:,1.  The mass arising from the right upper lip measures 5.7 x 4.4 x 6.7 cm with a heterogeneous appearance and enhancement pattern.  Hemangioma should be considered in the differential diagnosis as well as other mesenchymal neoplasms.,2.  MR angiography is suboptimal such that feeding vessels to the mass cannot be identified with certainty.
