摘　　要：目的探讨脑囊虫病的MRI表现及其诊断价值。方法收集分析21例经临床、病理证实的脑实质型囊虫病患者，常规使用SE和FSE序列并获取轴、矢、冠位及增强扫描图像，分析其各期MRI片征象及病理基础。结果21例患者中单发8例，多发13例，共计65个病灶。病灶主要分布于皮层及皮层下区。其中活动期5例，蜕变死亡期9例（早期3例，晚期6例），钙化期3例，混杂期4例。活动期MRI表现为囊性空腔和偏心头节，蜕变死亡期表现为“白靶征”，“多环、分层征”，钙化是病灶治疗后转归。结论MRI对脑虫病的定性、定位及定量具有很高的诊断价值。Objective To study MRI characteristics of cerebral cysticercosis, and its diagnostic value. Methods 21 cases with cysticercosis proved by clinic and pathology were collected. All cases were examined by MRI, including SE and FSE sequences at axial section, sagittal section, coronal section and contrast-enhanced scan. MRI findings and its pathological foundation were analysed. Results Of 21 cases,the lesions were single in 8, multiple in 13,totally 65 loci. The loci mainly distributed at the cerebral cortex and the subcortical area. The lesions were active stage in 5, decay stage in 9 （early stage in 3 and late stage in 6 ）, calcific stage in 3 and mixed stage in 4. Cysticercosis appeared as cystic lesions with a scolex in active stage, and showed as ＂white target sign＂ , ＂multi- ring sign,delaminated sign＂ in decay stage. Calcification was the consequence of cysticercosis. Conclusion Cerebral cysticercosis has characteristic manifestations on MRI. MRI is valuable in diagnosis of the quality,location and quantity of cysticercosis.
