Plain-English summary
An 8-month-old male Cocker Spaniel was brought in for severe limping on his right back leg, which was linked to his diagnosis of hemophilia A (a bleeding disorder). A CT scan revealed a large, abnormal mass in his thigh. Due to the pain and lameness, the vet performed surgery to remove the mass. The dog healed well and regained full use of his leg within 8 weeks. The mass turned out to be a chronic organized hematoma, similar to a condition seen in humans.

Abstract
An 8-month-old male, entire Cocker Spaniel dog was referred for investigation of severe right pelvic limb lameness. Previous history included a diagnosis of hemophilia A. On CT, a large, heterogeneous, rim-enhancing soft tissue mass was affecting the right thigh. Given the severe lameness and pain, surgical resection was performed. The dog recovered uneventfully, returning to full limb function within 8 weeks. A chronic organized hematoma was confirmed histologically, resembling a hemophilic pseudotumor described in humans. This case describes the imaging findings, treatment, and outcome of an atypical presentation of a muscular hemophilic pseudotumor in a dog.
