目的　研究小儿头部CT呈肉芽肿样改变的常见病因。方法　通过临床症状、体征、结合头部CT、血常规、结核菌素试验、X线胸片、脑脊液常规生化检查及血和脑脊液间接凝集试验等检查 ,并结合试验治疗确定病因。结果　 2 8例患儿中符合脑囊虫 15例 ,脑脓肿 8例 ,脑结核瘤 5例。结论　凡小儿头部CT显示肉芽肿样改变者应首先鉴别是否患脑囊虫、脑脓肿、脑结核瘤 Objective To study the common causes of granuloma-like changes in pediatric head CT. Methods The clinical symptoms, signs, combined with head CT, blood tests, tuberculin test, X-ray, cerebrospinal fluid routine biochemical tests and blood and cerebrospinal fluid indirect agglutination test and other tests, combined with experimental treatment to determine the cause. Results Among the 28 cases, 15 cases were identified as cerebral cysticercosis, 8 cases with brain abscess and 5 cases with brain tuberculoma.
