title: Acute encephalopathy with bilateral striatal necrosis. A distinctive clinicopathological condition.
abstract: Two patients with acute encephalopathy with bilateral striatal necrosis are presented and the literature on the subject is reviewed. The disease is characterized by abrupt onset following a systemic infectious illness, with disturbance of consciousness, absence of speech, dystonic movements of the limbs, general stiffness, opisthotonus, tremor, facial grimacing, and stereotyped reaction to painful stimuli. After a variable period of time, there is gradual improvement of the neurological status with clearing of consciousness and recovery of motor functions. Mild CSF pleocytosis is the only abnormal laboratory test encountered. Cranial imaging shows from the beginning of the illness, bilateral involvement of the striatum that may persist indefinitely. The pathogenesis of this disorder remains unknown although an infectious or para-infectious mechanism seems to be the most likely possibility.
