A hemophilia is a well known hereditary disorder of blood coagulation which bleeds mostly in the large jointsand frequently in central nervous system, abdominal ortans and soft tissues. Recently using combined CT and ultrasonography, more accurate location and extent of the lesion can be detected. Authors views proven 36 cases of hemophilia with analysis of their simple X-ray, CT and ultrasonography. The results were as follows: 1. All 36patients were male, and age distribution was 2-16 year. 2. Most patients showed type A (97.2%), and type B (2.8%)in 36 cases. 3. A hemophilia arthropathy(30 cases) was developed mostly hemophilia in the knee joint (67%), and rest of involvement in the elbow, ankle and hip joint. 4. On CT of CNS lesion(14/36 cases); ICH in 6 cases(43%),EDH in 2 cases(14%), combined type in 3 cases(21%) and SAH in 3 cases(21%). 5. Ultrasonography, retroperitoneal hematoma were detected in 4 cases, including ileopsoas hematoma(2 cases).
