Haemophiliac pseudotumors are usually observed in the diaphysis of long bones. Pseudotumors due to psoas muscle hematoma are rare and surgical management is difficult. Surgical treatment of these lesions is usually associated with high morbidity and mortality rate. Here, we present a case with iliopsoas haemophiliac pseudotumors with bowel fistulization who underwent three abdominal operations and survived. Based on our experiences in this patient, we recommend to wait for the intraabdominal hematoma and adhesions to resolve and organise, so that the dissection can be kept to a minimum, which decreases the chances of iatrogenic injury and surgical bleeding (Fig. 3, Ref. 15).
