Bilateral basal ganglia lucencies following acute febrile illness.

Bilateral striatal necrosis in children without damage elsewhere in the brain can present as an acute neurological disorder or as a progressive disorder. Three children of 6, 7 and 12 years age developed dystonic posture of limbs without any cranial nerve involvement or alteration of sensorium soon after recovery from acute high grade febrile illness of 3-4 days duration. Computerized tomographic scan of head showed bilateral necrosis of basal ganglia. We think that these patients probably constitute a clinically and radiologically distinct subgroup of disorder that produce bilateral striatal necrosis in children. The cause of the syndrome is unknown.
