| History |
A 76 year-old man presented with two months of progressive confusion, vision loss, and left-sided weakness. His medical; history was notable for hypothyroidism, type 2 diabetes mellitus, coronary artery disease, basal cell carcinoma of the; forehead status-post excision, deep vein thrombosis, and several years of recurrent dyspnea. Two months prior to neuroophthalmology; evaluation, he was hospitalized for dyspnea, and lung biopsy revealed non-necrotizing granulomas.; Corticosteroids were initiated for pulmonary sarcoidosis. He was readmitted 1 month later for dyspnea after corticosteroid; taper and complained of difficulty reading text messages. Neurologic examination revealed a right homonymous; hemianopia. MRI brain revealed multifocal T2 hyperintensities without enhancement, and CSF evaluation demonstrated; isolated elevated protein of 77 with negative cytology and oligoclonal bands. MRI cervical spine showed two chronic nonenhancing; cord lesions. Five doses of intravenous methylprednisolone 1g daily were administered; he was discharged on; prednisone 20mg without improvement in neurologic symptoms. At his neuro-ophthalmology consultation two weeks after; discharge, he had developed worsening left hemiparesis, inability to read, and needed assistance with daily activities.; Examination was most pertinent for a generalized encephalopathy, visual acuity of only 20/90 OD and 20/100 OS with; single optotypes, right homonymous hemianopia, inability to draw a clock, and perseveration. Within 1 week of evaluation,; he was hospitalized due to falls, incontinence, and left hemiparesis. MRI brain in November demonstrated increased size of; the multifocal T2 hyperintensities without enhancement. Broad serum work-up was notable for positive ANA 1:160; (homogenous pattern) and P-ANCA (negative on repeat testing), mildy elevated ACE, and low CD3/CD8 count. CSF; evaluation showed protein of 66, but was otherwise normal, including flow cytometry, JC virus PCR, and autoimmune; encephalopathy panel. PET CT skull to thigh showed reduced FDG uptake corresponding with MRI brain lesions and no; areas of increased FDG uptake. A diagnostic procedure was performed. |
