Small ventricles detected by CT-scanning in epileptic patients.
Relatively young 119 cases of generalized epilepsy and 99 controls of an identical age were selected. The bicaudate CVI was measured and the results were as follows: 1) In our cases, the mean of bicaudate CVI showed a smaller value than those of Hahn's in both epilepsy and control groups. 2) When the value of bicaudate CVI was set up below the point of 8.5 as "excessively small ventricle," the incidence rate of "excessively small ventricle" was 9% in the control group and 31% in the epilepsy group. The data showed higher incidences of small ventricles in the epilepsy group, and that the younger females have a tendency to have higher incidences of small ventricles. 3) To make clear the reason for the higher incidences of small ventricles in epilepsy, the small ventricle group and the non-small ventricle group in epilepsy were compared with each other from the points of the clinical course, EEG findings and frequency of attacks. No correlation or difference between them was found. Further investigation will be needed to make clear the etiology of small ventricles in epilepsy. However, it could be said at the present stage that not so many atrophic changes were observed in the younger patients of generalized epilepsy.
