Role of Radiotherapy in Hemophilic Pseudotumor of the Orbit

Abstract

Hemophilic pseudotumor is an encapsulated, chronic, slowly expanding hematoma usually seen in 1–2% patients with severe coagulative disorder (). It usually occurs in soft tissues, muscles, tendons, and subperiosteal part of the bones. It slowly enlarges, develops a fibrous capsule, and destroys underlying tissues by progressive necrosis (). Hemophilia is an X chromosome-linked hereditary disorder caused by defective synthesis or synthesis of dysfunctional factor VIII molecules ().
