The examination was otherwise unremarkable.She was anemic (hematocrit 27.2%) with erythrocyte sedimentation rate (ESR) 115 mm/h and C-reactive protein (CRP) 3.3 mg/dl. Cerebrospinal fluid (CSF) was clear and colorless and showed a lymphocytic pleiocytosis (24 white blood cells with 93% lymphocytes) with mildly elevated protein (71 mg/dl) and normal glucose (51 mg/dl). Negative infectious studies of CSF included bacterial, fungal, and mycobacterial cultures, as well as venereal disease research laboratory test, PCR for herpes simplex virus, and cryptococcal antigen. Magnetic resonance imaging of the brain showed diffuse pachymeningeal thickening and enhancement (Figure 1A) without venous sinus thrombosis by computed tomography (CT) venogram.
