目的:笔者报道42例CT诊断的脑穿通畸形(包括先天性和继发性)着重讨论其发病机理,起因,CT特征和CT诊断价值。CT表现为大脑半球内与脑室或/和蛛网膜下腔相通的囊腔。此囊腔共有三种类型:(1)脑实质——脑室型;(2)脑实质——蛛网膜下腔型;(3)混合型,其密度与脑脊液相若,(?)者并就CT上脑穿通畸形与脑软化灶,局部脑萎缩,颅内囊性病变的鉴别诊断进行了分析。
Objective: The author reports 42 cases of CT diagnosis of brain penetration through deformity (including congenital and secondary) focuses on its pathogenesis, causes, CT features and CT diagnostic value. CT showed cystic cavity in the cerebral hemisphere and ventricular or / and subarachnoid space. There are three types of cyst: (1) parenchyma - ventricle type; (2) parenchyma - subarachnoid type; (3) mixed type, its density and cerebrospinal fluid similar to CT perforated brain deformities and cerebral softening lesions, local brain atrophy, differential diagnosis of intracranial cystic lesions were analyzed.
