Objective To report the diagnosis and treatment of a radial artery pseudoaneurysm in a cat. Study Design Clinical report. Animal M aine C oon cat (8‐year‐old neutered male). Methods Ultrasonographic and angiographic examination of a fluctuant, nonpainful, 3 cm × 1.5 cm subcutaneous swelling on the craniomedial distal aspect of the right radius that occurred 40 days after suspected cat bite trauma was consistent with a radial artery pseudoaneurysm. After ligation of the radial artery proximal to the lesion, the pseudoaneurysm was surgically excised. Results The excised tissue had hemorrhage and fibrin surrounded by a thick fibrous granulating capsule of variably mature fibroblasts and focal areas of inflammatory cells (lymphocytes, plasma cells, and macrophages) consistent with a pseudoaneurysm. Surgical excision resulted in resolution of clinical signs. Conclusions Ultrasonography enabled prompt, noninvasive diagnosis of pseudoaneurysm. Angiography or computed tomography may be useful to aid diagnosis and assess the collateral blood supply to the manus before surgical treatment.
