Fig 3. T2-weighted MR images of an 18-year-old man at disease onset with encephalitis of unknown etiology and refractory status epilepticus. Findings of the left image (day of hospital admission) are normal. The right image (11 months later) shows an enlargement of the ventricles and of the subarachnoid space.
