A yearling Thoroughbred colt was admitted to the University of Florida College of Veterinary Medicine with severe, progressive lameness of the left forelimb. A centrally located expansile lytic lesion involving approximately 40% of the distal phalanx with a large associated vascular channel was identified by radiography. Increased vascular phase pooling, increased soft tissue phase uptake, and a photopenic area on bone phase images corresponding to the lytic lesion within the left distal phalanx were identified by vascular, soft tissue, and bone phases of a three phase bone scan, respectively. Contrast medium accumulation and disappearance in dilated vessels within the lesion was apparent angiographically. The colt was euthanized and the histologic diagnosis was hemangioma of the distal phalanx with a pathologic fracture.
