Voiding dysfunction due to chronic viral encephalitis in a young woman.

We record a case of a 37-year-old female with acute viral encephalitis, frequency and urgency incontinence. Video urodynamics showed small bladder capacity, sensory urgency, high residual urine and a Christmas tree appearance of the bladder. MRI showed inflammation and edema in the area of the thalamus and internal capsule in the early stage, then cavitation and gliosis in the same regions in the late stage.
