Synovial Hemangioma Accompanied by Cruciate Ligament Injury in a Dog

抄録

We report here the clinical presentation and successful surgical management of synovial hemangioma accompanied by cruciate ligament injury in a dog. Surgical correction of cruciate ligament injury was performed after removing torn cruciate ligaments, synovial mass and masses attached to the ligaments and distal femoral articular cartilage. At 10 months, the dog has showed no evidence of recurrence in the stifle joint. Synovial hemangioma, although a seemingly rare cause of stifle joint pathology, should be considered in the differential diagnosis for cruciate ligament injury when a circumscribed intra-articular soft tissue mass is evident radiographically with cranial or caudal drawer motion. This is the first case report in a dog to describe synovial hemangioma accompanied by cruciate ligament injury.
