结果所有病例均出现了低密度灶。
方法：以头颅CT扫描观察脑室周围低密度灶并按GOTO方法分型。
METHODS: Low - density focus around ventricle were observed with skull CT scanning and classified according to GOTO classification.
CT改变为脑变性及继发性脑萎缩，表现为形状及大小不一的低密度灶。
The CT changes are cerebral degeneration and secondary cerebral atrophy, manifested as low density focus different in both shape and size.
