HEMOPHILIC PSEUDOTUMORS: A RARE COMPLICATION OF HEMOPHILIA

Background:Hemophilic pseudotumor is a rare but potentially severe complication of hemophilia, seen in 1 2% of patients with severe forms of the disease, particularly in the absence of early prophylactic treatment. These lesions present as slowly expanding, encapsulated hematomas, most commonly located in long bones. Case Presentation:We report the case of a 38-year-old man with severe hemophilia A under prophylactic factor VIII therapy, who developed a right iliac bone pseudotumor complicated by an iliopsoas hematoma. CT revealed multiloculated hemorrhagic collections eroding the iliac bone and compressing adjacent organs. Surgical drainage and resection were performed under factor VIII coverage, with favorable postoperative outcomes. Conclusion:Although rare, hemophilic pseudotumor should be considered in patients with hemophilia presenting with erosive bone lesions or soft tissue masses. Imaging plays a key role in diagnosis and management planning.
