Progressive idiopathic strio-pallido-dentate calcinosis (Fahr's disease) with autosomal recessive inheritance. Report of three siblings.
3 siblings with symmetrical calcifications in the strio-pallido-dentate system are described. Parathyroid function was normal and there were no signs of central or peripheral myelinopathy. This is the 9th family reported with autosomal recessive idiopathic strio-pallido-dentate calcinosis and the first to be investigated by computerized tomography (CT). CT scans appeared to be superior to plain skull radiograms to assess the localization and the extent of the calcifications in vivo. The calcifications were the least extensive in the youngest and the most extensive in the eldest. It is suggested that the calcifying process is a progressive disorder. It seems to start in the dentate nuclei and pons, and subsequently extends to the basal ganglia and to the radiation of the corpus callosum.
