共查31例次，其中脑积水7次，脑室扩大2次，低密度病变9次，脑肿胀3次，脑室室管膜增强2次，结节、钙化、脑萎缩、脑膜增强各1次。

Total examinations were 31 times . CT scans showed hydrocephalus in 7 , enlarged ventricles in 2 , hypodense lesions in 9 , cerebral edema in 3 , ventricular enhanced ependyma with contrast in 2 , intracerebral nodules , calcification , cerebral atrophy and enhanced meninges one time respectively .

认为CT及MRI均能显示四脑室以上扩大，但四脑室扩大明显，均无增强效应。

CT and MRI could reveal the ventricular enlargement above the fourth ventricle , but the enlargement of the fourth ventricle was more significant , both without contrast enhancement effect .
