Abstract

SummaryNecropsy examination of an 8-year-old female swamp wallaby (Wallabia bicolor) from a zoological garden revealed four intestinal diverticular outpouchings at the mesenteric border of the jejunum, which were partly ruptured causing a fatal peritonitis. Microscopically, affected small intestinal segments were characterized by an abrupt gap in the muscular layer with subsequent herniation of respective mucosal and submucosal layers, interpreted as acquired pseudodiverticula. Multifocal perforations of these diverticula were associated with prominent fibrinosuppurative serositis with leakage of ingesta. In addition, there was intestinal nematodal endoparasitism with accompanying neutrophilic to eosinophilic enteritis. Small intestinal pseudodiverticula resembling human colonic diverticulosis are rare in animals and can lead to fatal peritonitis by faecal impaction, subsequent transmural inflammation and eventual perforation.
