Resumo
Background: Neoplasia of the urinary bladder is common in dogs, accounting approximately 0.5 to 1.0 percent of all neoplasms. Most of the neoplasia of the urinary bladder is epithelial in origin and only 10% of urinary bladder neoplasms in dogs are from mesenchymal origin, of which the most frequent types are leiomyoma / leiomyosarcoma, and hemangioma / hemangiosarcoma. Virtual autopsy refers to the postmortem use of radiology, ultrasound and cross-sectional imaging prior to conventional necropsy. This paper reports the detection of a rare extra-luminal urinary bladder mass diagnosed as leiomyoma with a virtual autopsy techniques.Case: A 16-year-old male Schnauzer had previous history of seizure and no complains related to the urinary system. The animal was treated symptomatically to the neurological signs and responded to medical treatment. Nine weeks later from the first visit to the hospital the dog was found dead at home. Then postmortem ultrasound and computed tomography of the abdomen were performed. Postmortem ultrasound revealed a homogenously hypoechoic, rounded and slightly irregularly marginated mass located externally but adjacent to the left cranial wall of the urinary bladder and appears to extend from its serosal margins. Postmortem computed tomography was performed after postmortem ultrasound. A pedunculated homogenous soft tissue attenuating mass was located at the left lateral aspect of the urinary bladder and extended cranially. It had a stalk that connected to the left lateral wall of the urinary bladder. A partial necropsy of the abdomen was done just to examine the mass. A round extraluminal, pedunculated mass was observed at the left lateral aspect of the urinary bladder wall. It was pale pink on the outside and white inside, with a soft to firm consistency. The lumen and mucosal surface of the urinary bladder was smooth and regular...(AU)
