Here we represented the clinical and pathological features of a patient with little response to steroid before definite diagnosis. The 50-year-old male had a fluctuating disease course for more than 3 years. He presented visual disorders, seizure, cognitive impairment, hypersomnia, unsteady gait, dysphasia, dysphagia, and incontinence. Magnetic resonance imaging showed multiple, supratentorial and infratentorial abnormal signals, while cerebrospinal fluid and cerebral angiography were normal. Magnetic resonance spectrum showed a decrease of N-acetyl-aspartate. Brain biopsy revealed nongranulomatous lymphatic vasculitis with reactive gliosis, cicatrization, demyelination and focal hemorrhages.展开更多
