Abstract:
An 11-month-old entire male Rottweiler was referred for further investigation of raised, soft, compressible, non-pulsatile, subcutaneous tubular structures along the right antebrachium that had been diagnosed to be a vascular malformation on histopathology of a subcutaneous biopsy. Computed tomographic (CT) with angiography did not reveal an arteriovenous malformation or fistula. Ultrasonography of the limb demonstrated a venous malformation with thrombi and phleboliths. An MRI study of the limb was consistent with a venous malformation with small rounded luminal signal voids that were confirmed to be phleboliths. Radiography at follow-up demonstrated phleboliths. This is the first report describing the combined CT, ultrasonographic, MRI and radiographic characteristics of venous malformation with phleboliths in a limb of a dog.
