Determining the precise etiology of an intraventricular mass can be a difficult diagnostic problem. CT and angiographic findings were reviewed in a series of 73 patients who had intraventricular masses. The histologic diagnosis can be suggested preoperatively by an analysis of the frequency of lesions occurring at a given ventricular location, lesion density before and after administration of contrast material, age and sex of the patient, morphologic appearance of the mass, and presence or absence of hydrocephalus. Angiography is useful when meningioma, choroid plexus papilloma and carcinoma, or arteriovenous malformation are considered. The differential features of each diagnostic entity are discussed.
确定脑室内肿块的确切病因可能是一个困难的诊断问题。我们回顾了73例患有脑室内肿块患者的CT和血管造影检查结果。通过分析特定脑室部位出现病变的频率、使用对比剂前后的病变密度、患者的年龄和性别、肿块的形态外观以及是否存在脑积水，可以在术前推测组织学诊断。当考虑为脑膜瘤、脉络丛乳头状瘤和癌或动静脉畸形时，血管造影很有用。文中讨论了每种诊断实体的鉴别特征。
