Abstract

A 30 year-old woman developed a postural and rest tremor of the left hand following a right peduncular post-traumatic hematoma. Two years later, positron emission tomography showed a marked decrease in [18F] fluorodopa uptake contrasting with a normal [76Br] bromolisuride uptake in the right striatum. This suggests that: 1) chronic unilateral dopaminergic striatal denervation may occur without persistent D2 dopaminergic receptor upregulation in humans; and 2) symptomatic mesencephalic tremor may be, at least in part, related to dopaminergic striatal denervation.
