Summary
Synovial hemangioma, a rare vascular tumor, caused chronic lameness in a dog. Surgical excision via arthrotomy successfully treated the condition, resolving the lameness and hemarthrosis.
Area of Science:
- Veterinary Medicine
- Surgical Oncology
- Diagnostic Imaging
Background:
- Synovial hemangioma is a rare, benign vascular tumor that can affect joints.
- It may present as a soft tissue mass, leading to lameness and joint effusion.
Observation:
- A Standard Poodle presented with a two-month history of recurrent lameness and hemarthrosis in the left stifle.
- Radiographs revealed a soft tissue density mass, and diagnostic arthroscopy confirmed its location within the joint capsule.
Findings:
- Histologic evaluation confirmed the mass as synovial hemangioma, characterized by cavernous vascular spaces filled with erythrocytes.
- Surgical excision via arthrotomy resulted in complete resolution of clinical signs.
Implications:
- Synovial hemangioma should be considered in the differential diagnosis for dogs with chronic, non-traumatic lameness and hemarthrosis, especially when a joint mass is detected.
- Arthroscopic diagnosis and surgical excision are effective treatment modalities for canine synovial hemangioma.
