Findings

Two lateral radiographs are available for review. There is a fat opacity mass arising from the distal extremity of the spleen, with a thin soft tissue border. The mass is located in the cranioventral abdomen caudal to the liver and spleen. No urinary calculi are visible. There is a linear structure in the cranial retroperitoneal space that may represent ureter, which was distended on ultrasound exam. The liver is mildly enlarged and extends beyond the costal arch. The remainder of the abdominal organs appear normal.
