Findings

The stomach is markedly enlarged and filled with fluid and gas. There is mineral opacity material with a sharp edge in the body and pylorus. There are small mineral opacities (gravel sign) in the dependent portion of the stomach. The enlarged stomach is causing a mass effect and displacing the other organs caudally, however peritoneal detail is good.
