Abstract

A [18F]-FDG PET study was performed in a 44 year old man with proximal kinesigenic choreoathetosis (PKC) secondary to idiopathic primary hypoparathyroidism (IPH) before and 1 year after calcium/calcitriol therapy. The [18F]-FDG PET performed before the start of the therapy disclosed a significant bilateral hypometabolism in the ventral striatum. One year later, with the patient still under calcium/calcitriol therapy and free of any occurrence of PKC episodes, the [18F]-FDG PET did not show the previously detected hypometabolism. The hypometabolism of the ventral striatum secondary to hypocalcaemia seems to play a crucial part in the pathogenesis of paroxysmal kinesigenic choreoathetosis associated with IPH.
