Abstract

　　Purpose：To explore the diagnostic value of MRI for cerebral cysticercosis and analyse MRI manifestations of cerebral cysticercosis.

　　Methods：Characteristic MRI appearances and potential pathological changes of 703 patients with cerebral cysticercosis verified by MRI and clinic were retrospectively analysed. MRI examinations of brain were performed with a superconductive 1.0T MR Unit from Siemens，and SE sequence was used in all patients. MRI findings were compared with plain cerebral CT in 456 cases of them.

　　Results：According to the features of MRI and the potential pathology of cerebral cysticercosis，there are four types，including cerebroparenchymal type （n＝561），intraventrical type （n＝86），meningeal type （n＝21） and mixed type （n＝35），and four stages，including alive stage （n＝313），degenerative death stage （n＝106），non－alive stage （n＝101） and mixed stage （n＝183）. Calcification lesions were found in 86 cases with CT，40 cases with MRI of 456 cases accompanied CT. Cysticercosis lesions non－exhibited on plain cerebral CT in 19 cases were totally found on MRI.

　　Conclusion：MRI is the most effective mageological method for diagnosing cerebral cysticercosis in alive stage and degenerative－death stage. However，CT is superior to MRI for revealing non－alive stage calcification of cysticercosis. Both MRI and CT were used in the meantime，accurate staging and classification of cerebral cysticercosis could be obtained，it is important for doctor to guide the chemical therapy.

　　囊虫病是人体吞服猪绦虫卵经胃液消化孵化出幼虫，移位于人体组织中所引起的寄生虫病。脑、横纹肌、眼和皮下组织是其好发部位。移位于脑部者称为脑囊虫病，占囊虫病的60～90％^[1]。脑囊虫病临床表现并无特异性，病原体免疫学检查和影像学检查是诊断脑囊虫病的主要手段。以往影像学诊断脑囊虫主要依靠CT检查，磁共振成像（MRI）的临床应用为脑囊虫病的诊断提供了新方法。本文旨在探讨MRI对脑囊虫病的诊断价值和脑囊虫病的MRI表现。
