Renal haemangioma in a dog

A three-and-a-half-year-old, spayed female, crossbred dog was presented with chronic haematuria. Diagnostic tests included abdominal ultrasonography, intravenous urography, cystoscopy and nephrectomy. Renal haemangioma was identified as the cause of the haematuria, which resolved postoperatively. A subcutaneous mass developed one month after the nephrectomy, which was diagnosed by biopsy as a cutaneous cavernous haemangioma. No other masses were reported one year later.
