小儿脑囊虫病的CT临床研究

CT Manifestations of Cerebral Cysticercosis in Children

目的：通过本研究探讨小儿脑囊虫病的ＣＴ临床特点。材料和方法：１９９５年９月至１９９６年１２月经ＣＴ检查及临床抗囊虫治疗证实的该病患儿１０２例。结果：（１）ＣＴ检查以小环形或结节强化型最多见（占９４％），病灶单发（占９５％），发病部位以大脑皮层区顶叶多见（占７９％）。小环形或结节影在边界清晰锐利的低密度区内偏心存在，无占位效应。延时扫描示强化病灶持续较久，适合小儿安全缓慢给药要求。（２）临床患儿多以各种类型癫痫发作及发作后一过性肢体瘫痪就诊。血清囊虫抗体阳性判定标准有较高的假阴性。采用中西药物结合治疗疗程短，见效快。结论：小儿脑囊虫病ＣＴ的主要表现形式薄壁环形增强伴有病灶周围水肿。

PURPOSE:The purpose of this study is to analyze the CT features of cerebral cysticercosis in childrem.MATERIALS AND METHODS:One hundred and two cases of cerebral cysticercosis in children from September 1995 to December 1996 were reported. All cases were examined by CTand treated with anti-cysticercus drug. RESULTS:The CT manifestions of cerebral cysticercosis were:1 Ring-like or small nodular enhancement were the most common feature(94%)and are usually solitary(95%). The lesion commonly locates in the cortex of the parietal lobe(78%).The ring or small nodular lesion usually situated eccentrically within the edematous area with no mass effect. The enhanced ring focus can persist for a longer time in the delayed contrast film. 2. Clinically there are various patterns of epilepsy associated with hemiplegia after the seizue. Pseudonegative results are often seen in serum cysticercus antibody reaction.CONCLUSION:CT is an important imaging modality in the examination of cerebral cysticercosis.
