对52例因癫痫发作就诊,CT检查在脑内发现小脓肿的病例,手术切除标本进行了寄生虫学检查,证实为脑囊虫病患者。取脓肿壁作病理切片,病理检查发现5例囊虫仍存活并伸出头节,16例囊虫虽死亡但虫体尚完整,14例在切片中查见了虫体成分。结果表明病变组织的坏死和炎症反应以完整死虫组最显著;至囊虫残破炎症逐渐缓和,增生性变化渐占优势,脓肿腔缩小;有3例硬结纤维化;钙质沉积罕见。对脑内囊虫性小脓肿的形成以及病变与CT影像之间的相关性进行了讨论。
52 cases of epilepsy due to treatment, CT examination in the brain found small abscess cases, surgical specimens were parasite examination, confirmed as cerebral cysticercosis patients. The abscess wall was taken for pathological examination. Five cases of cysticercosis were still alive and extended out of the head section. Sixteen cases of cysticercosis were dead but the parasites were still intact. In the 14 cases, the parasites were found in the sections. The results showed that the necrosis and inflammatory reaction of the diseased tissue were the most significant in the complete necrosis group. The cysticercosis was gradually alleviated, the hyperplastic changes gradually dominated, and the abscess narrowed. There were 3 cases of induration fibrosis and rare calcification. The formation of cysticercosis and small abscess in the brain and the correlation between the lesion and the CT image were discussed.
