Infantile bilateral striatal necrosis following measles.

Abstract

A previously healthy 4-year-old boy presented with typical measles and demonstrated lesions confined to basal ganglia. The clinical symptoms were an abrupt onset, impaired consciousness and mutism, extrapyramidal signs and severe neurovegetative dysfunction. No modification of the cerebrospinal fluid was observed; laboratory tests were all normal with the exception of a positive serologic test for measles. Cranial magnetic resonance imaging showed abnormal signals in the striatum, affecting the putamen and the caudate nuclei bilaterally. Neurologic improvement occurred within 2 months, with regression of lesions on cranial imaging, suggesting that edema played an important role in the initial stage of the disease.
