摘　　要：目的探讨脑膜型脑囊虫病的MR影像表现特征。方法28例临床确诊为脑膜型脑囊虫病的患者,行MR平扫及增强扫描,回顾性分析其MR影像学表现。结果共发现病灶120个;位于脑沟、纵裂池的脑囊虫影像学表现典型,与脑实质型表现相似,可分为存活期、变性坏死期和纤维钙化期;位于外侧裂和基底池等处病灶表现不典型,可分为大囊型和葡萄状丛集型。结论脑膜型脑囊虫病MR表现复杂多样,正确认识其典型和非典型影像特征,对正确诊断及治疗具有重要意义。Objective To discuss the MRI manifestation of pial neurocysticercosis. Methods Twenty-eight patients with pial neurocysticercosis verified by clinic were retrospectively studied. All patients were performed with plain MR scan and contrast enhancement. Results There were 120 lesions found in subarachnoid space. Typical MRI manifestations llke parenchymal neurocysticercosis were found in lesions located in the sulcus and longititudinal fissure cistern. They could be identified as active stage, degenerative and necrotic stage, calcific stage. The MRI manifestations of the lesions located in lateral sulcus and basal cisterns were atypical and could be divided into larger cysts and racemose. Conclusion The manifestations of plal neurocysticercosis are complicated and various. It is important to recognize its typical and atypical maniflestations corretivelyin in diagnosis and therapy.
