Brain CT was made in 720 patients with tumors of the central nervous system. The subtentorial site of the process was encountered in 50.4% of cases. The paper outlines the skialogic characteristics of tumors having varying structures: medulloblastomas, ependymomas, astrocytomas, angioreticulomas, truncal gliomas, metastases, epidermoids, neurinomas, meningiomas, chemodectomas, arteriovenous malformations. Difficulties in determining the histostructure of tumors on the basis of skialogic manifestations were noted. Anatomic and skialogic approaches which may assume the type of neoplasmic process were outlined.
对720例中枢神经系统肿瘤患者进行了脑部CT检查。该病变幕下部位在50.4%的病例中被发现。本文概述了具有不同结构的肿瘤的影像学特征：髓母细胞瘤、室管膜瘤、星形细胞瘤、血管网织细胞瘤、脑干胶质瘤、转移瘤、表皮样囊肿、神经鞘瘤、脑膜瘤、化学感受器瘤、动静脉畸形。指出了根据影像学表现确定肿瘤组织学结构的困难。概述了可能推断肿瘤性病变类型的解剖学和影像学方法。
