Medical specialty:  Radiology
 MRI Brain to evaluate sudden onset blindness - Basilar/bilateral thalamic strokes.

CC:, Sudden onset blindness.,HX:, This 58 y/o RHF was in her usual healthy state, until 4:00PM, 1/8/93, when she suddenly became blind. Tongue numbness and slurred speech occurred simultaneously with the loss of vision. The vision transiently improved to "severe blurring" enroute to a local ER, but worsened again once there. While being evaluated she became unresponsive, even to deep noxious stimuli. She was transferred to UIHC for further evaluation. Upon arrival at UIHC her signs and symptoms were present but markedly improved.,PMH:, 1) Hysterectomy many years previous. 2) Herniorrhaphy in past. 3) DJD, relieved with NSAIDs.,FHX/SHX:, Married x 27yrs.

Transthoracic echocardiogram (TTE) showed an intraatrial septal aneurysm with right to left shunt. Transesophageal echocardiogram (TEE) revealed the same. No intracardiac thrombus was found. Lower extremity dopplers were unremarkable. Carotid duplex revealed 0-15% bilateral ICA stenosis. Neuroophthalmologic evaluation revealed evidence of a supranuclear vertical gaze palsy OU (diminished up and down gaze). Neuropsychologic assessment 1/12-15/93 revealed severe impairment of anterograde verbal and visual memory, including acquisition and delayed recall and recognition. Speech was effortful and hypophonic with very defective verbal associative fluency. Reading comprehension was somewhat preserved, though she complained that despite the ability to see type clearly, she could not make sense of words. There was impairment of 2-D constructional praxis. A follow-up Neuropsychology evaluation in 7/93 revealed little improvement. Laboratory studies, TSH, FT4, CRP, ESR, GS, PT/PTT were unremarkable. Total serum cholesterol 195, Triglycerides 57, HDL 43, LDL 141. She was placed on ASA and discharged1/19/93.,She was last seen on 5/2/95 and was speaking fluently and lucidly.

CC:, Found down.,HX:, 54y/o RHF went to bed at 10 PM at her boyfriend's home on 1/16/96. She was found lethargic by her son the next morning. Three other individuals in the house were lethargic and complained of HA that same morning. Her last memory was talking to her granddaughter at 5:00PM on 1/16/96. She next remembered riding in the ambulance from a Hospital.

Neuropsychologic assessment on 1/18/96 revealed marked cognitive impairments with defects in anterograde memory, praxis, associative fluency, attention, and speed of information processing. She was discharged home on 1/19/96 and returned on 2/11/96 after neurologic deterioration. She progressively developed more illogical behavior, anhedonia, anorexia and changes in sleep pattern. She became completely dependent and could not undergo repeat neuropsychologic assessment in 2/96. She was later transferred to another care facility against medical advice. The etiology for these changes became complicated by a newly discovered history of possible ETOH abuse and usual "anxiety" disorder.,MRI brain, 2/14/96, revealed increased T2 signal within the periventricular white matter, bilaterally. EEG showed diffuse slowing without epileptiform activity.

Facial sensation was decreased on the right side (V1 distribution).,Motor/Sensory/Coord/Station/Gait: were all unremarkable.,Reflexes: 2/2 and symmetric throughout. Plantars were flexor, bilaterally.,Gen Exam: unremarkable.,COURSE:, MRI Brain, 10/7/92, revealed: a large 6x5x6cm slightly heterogeneous, mostly isointense lesion on both T1 and T2 weighted images arising from the planum sphenoidale and olfactory groove. The mass extends approximately 3.6cm superior to the planum into both frontal regions with edema in both frontal lobes. The mass extends 2.5cm inferiorly involving the ethmoid sinuses with resultant obstruction of the sphenoid and frontal sinuses.,It also extends into the superomedial aspect of the right maxillary sinus. There is probable partial encasement of both internal carotid arteries just above the siphon. The optic nerves are difficult to visualize but there is also probable encasement of these structures as well. The mass enhances significantly with gadolinium contrast. These finds are consistent with Meningioma.,The patient underwent excision of this tumor by simultaneous bifrontal craniotomy and lateral rhinotomy following an intrasinus biopsy which confirmed the meningioma. Postoperatively, he lost visual acuity, OS, but this gradually returned to baseline. His 9/6/96 neuro-ophthalmology evaluation revealed visual acuity of 20/25-3 (OD) and 20/80-2 (OS). His visual fields continued to abnormal, but improved and stable when compared to 10/92. His anosmia never resolved.

Using an oblique approach to the spine, the L5-S1 level was addressed using an oblique projection angled C-arm in order to allow for perpendicular penetration of the disc space.  A metallic marker was then placed laterally and a needle entrance point was determined.  A skin wheal was raised with 1% Xylocaine and an #18-gauge needle was advanced up to the level of the disc space using AP, oblique and lateral fluoroscopic projections.  A second needle, #22-gauge 6-inch needle was then introduced into the disc space and with AP and lateral fluoroscopic projections, was placed into the center of the nucleus.  We then proceeded to perform a similar placement of needles at the L4-5, L3-4 and L2-3 levels.,A solution of Isovue 300 with 1 gm of Ancef was then drawn into a 10 cc syringe and without informing the patient of our injecting, we then proceeded to inject the disc spaces sequentially.
