目的　报道１２２ 例由ＣＴ头颅轴位扫描疑为囊虫病的患者，通过进行血清学检查，进一学确诊定为是囊虫病抑或是钩端螺旋体病。方法　采用显微镜凝集试验（ＭＡＴ）和酶联免疫吸附试验（ＥＬＩＳＡ）。结果　确诊６６ 例囊虫病，５１例钩端螺旋体病，两者完全阴性５例。结论　不典型病例，仅藉ＣＴ是不能确诊为囊虫病还是钩端螺旋体病的。因两者致病后临床症状有类似之处，早期感染ＣＴ表现也有相同。必须进行血清学检查，方能确诊 Objective To report 122 cases of patients suspected of cysticercosis by CT cranial axial scanning. Serological tests were conducted to determine if they were cysticercosis or leptospirosis. Methods Microscopic agglutination test (MAT) and enzyme-linked immunosorbent assay (ELISA) were used. Results of 66 cases of cysticercosis diagnosed, 51 cases of leptospirosis, both completely negative in 5 cases. Conclusions Atypical cases can not be diagnosed as cysticercosis or leptospirosis by CT alone. Due to the clinical symptoms of the two have similarities, early CT manifestations are the same. Serological tests must be carried out before they can be diagnosed
