摘要
目的 探讨CT及MRI对脑内海绵状血管瘤(CA)的表现和诊断价值.方法 收集资料完整经手术病理证实的36例脑内CA患者的CT及MRI资料,重点分析其影像学表现特征.结果 脑内海绵状血管瘤可位于脑内任何部位,单发病灶多见,周围无或轻度水肿,无占位效应,CT平扫为稍高密度影,钙化占68.7%,增强扫描大都无强化;MRI表现为桑椹状混杂高信号,周围有云絮状低信号环,增强后病灶大都无强化;MRA检查未见异常血管.结论 脑内海绵状血管瘤的MRI表现较有特异性,MRI对脑实质内CA的检出率优于CT检查,可明确诊断.
Abstract
Objective To explore CT and M RI scan technique in diagnosis of cerebral cavernous angiomas (CA). Meth- ods MRI findings of cerebral CA in 36 cases proved by operation and pathology were reviewed. Results The lesion of in- tracerebral cavernous hemangioma could be located in every region of the brain, which single lesion was more often and mosl lesions had no or slightly edema without space - occupying effect slight hyperdensity mass were appeared in plain CT scan, and calcification were seen in of the 68.7% mass, the most of them were shown without enhancement. The characteristic MRI features were multiberry - like inhomogeuous intensity with flocculnt hypointensity ring. No enhancement could be seen. There were normal appearance in MRA. Conclusion For cerebral cavernous angiomas can be dignosed by CT and MR imaging fetures and MR scan is advantage than CT scan.
