摘　　要：分析了１２９例颅内肿瘤瘤周水肿的ＣＴ表现及其与肿瘤的大小、良恶性、囊性变、皮层破坏现象的关系。提出了瘤周水肿的ＣＴ分型，结果表明脑膜瘤以Ｂ１型水肿为主，转移瘤则以Ｂ２型常见，胶质瘤以Ｂ１型占优，Ｂ２型居次。脑膜瘤水肿很少向内囊部扩展，转移瘤水肿累及胼胝体及皮层不常见。作者认为，根据瘤周水肿的ＣＴ分型结合肿瘤水肿的各自特点，对脑膜瘤、胶质瘤及脑单发转移瘤的定性诊断有一定的帮助。CT appearences of peritumoral edema in 129 cases were described,the relations between theedema and the tumorous size,malignency,cystic formation,or the cortical invasion were assessed.We putforward the edema classification based on its CT appearences,the result suggested that type B1 was frequentin meningiomas,type B2 often seen in metastases,and in gliomas the edema might be either B1 or B2。Ourdeta indicated that the edema involved hardly in the internal capsule in meningiomas,and it did not cross thecorpus callosum and cortex in metastases.According to our observation,peritumoral edema is a helpful signin differental diagnosis between intracranial tumors.
