目的 探讨颅内包虫病的CT表现。方法 分析经手术、病理证实的 6例颅内包虫病的CT征象 ,其中单发脑内包虫囊肿 3例 ,多发 1例 ,硬膜外包虫囊肿 1例 ,肝脑多发泡型棘球蚴病 1例。结果 颅内包虫病一般表现为典型囊肿性病变 ,轮廓清晰、锐利 ,CT值与脑脊液相似 ,囊内容物密度均一 ,囊壁无或轻度增强。脑泡型棘球蚴病无特异CT征象 ,有时表现酷似脑胶质瘤。结论 CT是诊断颅内包虫病简捷、准确的影像学检查方法 ,密切结合临床资料正确诊断多无困难。
Objective To investigate the CT findings of intracranial echinococcosis. Methods CT findings of 6 cases of intracranial echinococcosis confirmed by operation and pathology were analyzed. Among them, 3 cases were single intraciliary hydatid cyst, 1 case was multiple, 1 case was epidural hydatid cyst, 1 was hepatic encephalic multilocularis echinococcosis example. Results Intracranial echinococcosis generally showed typical cystic lesions, the outline was clear and sharp. The CT value was similar to that of cerebrospinal fluid. The cyst contents were uniform and the cyst wall was not or slightly enhanced. There are no specific CT signs of cystic alveolar echinococcosis, sometimes manifesting like brain glioma. Conclusion CT is a simple and accurate imaging method for the diagnosis of intracranial hydatid disease, and it is more difficult to diagnose the intracranial hydatid disease with accurate diagnosis based on clinical data.
