6 year old Jack Russell Terrier

Findings

On the right lateral and v/d projections, the stomach is enlarged and fluid-filled. The remainder of the abdomen appears normal.

On the left lateral projection, the pylorus is filled with gas, which highlights a soft tissue mass. The mass is near the origin of the duodenum, and is likely fixed in the pylorus as it is on the non-dependent side.

On ultrasound, the stomach was filled with fluid. There was a hyperechoic soft tissue mass in the pylorus, that was well circumscribed and confined to the mucosal wall layers. There was no wall thickening in any other part of the stomach.
