大脳基底核石灰化CT像と臨床症状との対比

We investigated the relationship between the frequency of basal ganglia calcification appearing in CT scans and clinical symptoms in 3,599 patients. Basal ganglia were calcified in eleven patients (0.3%), of whom seven had calcification of the bilateral G. Pallidus, but no clinical symptoms. A relationship between calcification and clinical symptoms was shown in two patients under ten years old, a three-year-old with young brain atrophy and a six-year-old with a gonadotropin-producing brain tumor. Especially in patients over forty years old, a direct relationship between G.P. calcification and clinical symptoms was not shown, and calcification was considered to be pyhsilogical.
