Today’s case is an 11-year-old Old English Sheepdog with 1-week history of vomiting undigested food once daily. What is your interpretation?
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.
pyloric outflow obstruction (mass, stricture, polyp, granuloma)
Pyloric outflow obstruction due to stricture and scar/muscular hypertrophy, presumed secondary to previous GI ulceration. A pyloroplasty was performed to relieve the obstruction.
