[Retroperitoneal hematoma in children with hemophilia].

The cases of two boys with hemophilia and retroperitoneal haematoma are presented; the diagnosis was confirmed by means of ultrasound scanning. The clinical picture of retroperitoneal haematoma can not be distinguished from other acute abdominal conditions (retroperitoneal infiltrate, or abscess). These pathological processes require surgical treatment, whereas such one in the patients suffering from haemophilia with retroperitoneal haematoma is contraindicated. The diagnosis of retroperitoneal haematoma can be confirmed with a great certainty by means of ultrasound scanning.
