This is a unique case describing hydrocephalus to be the primary
presenting symptom of neurosarcoidosis. A 49-year-old woman with
previous ischemic cerebral events presented with a gait disorder,
urinary incontinence and cognitive impairment. Imaging showed
obstructive hydrocephalus, progressive white matter abnormalities and
basal leptomeningeal enhancement. Further diagnostics suggested
sarcoidosis.
