脑裂头蚴病四例报告及文献复习

Cerebral sparganosis： a report of 4 cases and review of literatures

目的探讨脑裂头蚴病的临床表现、影像学特点以及治疗方法和效果。方法结合文献复习回顾性分析4例经病理确诊的脑裂头蚴病例特点。结果脑裂头蚴病临床表现以癫痫、轻偏瘫和头痛多见。CT表现特点为低密度灶伴点状钙化，不规则或点状强化。MRI可见病灶区有串珠样增强或扭曲的条索样增强影。本组4例中3例在CT定位行立体定向活检，1例手术开颅取出，预后均良好。结论CT引导下立体定向活检在诊断和处理脑裂头蚴病中起到重要作用。

Objective To explore the clinical manifestations, imaging features and treatment of cerebral sparaganosis. Methods The characteristics of 4 cases definitely diagnosed as cerebral sparganosis by pathology were retrospectively analyzed. Results The main clinical presentations of cerebral sparganosis included seizures, hemiparesis and headache. Characteristics of CT contained low-density lesions with punctate calcifications, irregular or punctate intensifications of lesions on the follow-up CT images. MRI showed bead-shaped or tortuous cordlike enhanced images in the region of lesions. Among the 4 cases in this study, 3 underwent CT-guided stereotactic biopsy and 1 underwent craniotomy for surgical removal of lesions; all cases have a favorable prognosis. Conclusion CT-guided stereotactic biopsy plays a significant role in diagnosing and treating cerebral sparganosis.
