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 explore the features of MR imaging of meningeal cysticercosis. Methods Twenty-eight patients with clinically diagnosed meningeal cysticercosis were examined by MR plain scan and contrast-enhanced MR scan. The MR findings were retrospectively analyzed. Results A total of 120 lesions were found. The cerebral cysticercosis located in the sulci and longitudinal fissure pool was typical and similar to the brain parenchyma, which could be divided into the stages of survival, degeneration and necrosis and fibro-calcification. Lesions atypical, can be divided into large capsule and grape clusters. Conclusion MR manifestations of meningeal cysticercosis are complex and diverse, and correct understanding of the typical and atypical features of the images is of great significance for the correct diagnosis and treatment.
