An 18-month-old La Mancha wether was evaluated for progressive anorexia and lethargy of two weeks duration. Previous medical history had included suspected copper toxicity. Radiographs highlighted a distended rumen, and a rumenotomy yielded uniform ingesta devoid of normal stratification. The client elected for euthanasia and on postmortem examination an abomasal obstruction was identified. Histopathology demonstrated the presence of a pyloric hamartoma. This case describes the clinical presentation, clinical pathology, diagnostics and postmortem examination of a partial pyloric outflow obstruction in a goat due to a pyloric hamartoma.
