Introduction The aim of the study was to describe three canine cases of intramural pyogranuloma of the intestine associated with intestinal obstruction.
Methods and results. Two dogs were presented with a history of weight loss and vomiting of one-month’s duration and the third dog had vomiting and diarrhoea of one-week’s duration. On physical examination, an abdominal mass was detected in all cases. Abdominal radiography demonstrated the presence of soft tissue opacity in two dogs and air filled dilated intestinal loops in all three dogs. Abdominal ultrasound depicted hyperkinetic viscous filled dilated intestinal loops and a hypoechoic small intestinal mass in all dogs. Intestinal corrugation was also noted in one dog. Exploratory celiotomy confirmed the presence of a jejunal mass, which was removed by resection and anastomosis in all dogs. In one dog, a linear foreign body was also found cranial to the mass and removed through a separate enterotomy incision. On histologic examination, multifocal pyogranulomatous lesions were observed, extending from the muscular layer into the submucosa and the mucosa in two dogs and localised into the muscular layer in the third. In one dog foreign material consistent with plant fragments was observed embedded in the muscular layer and circumscribed by fibrous tissue within the pyogranulomatous lesion. Two dogs recovered without complications and are doing well two and three years post surgery respectively, while the third showed signs of septic peritonitis four days post surgery and was euthanised on the owner’s request but permission for necropsy was denied.                     Conclusions Intestinal pyogranulomas should be included in the differential diagnosis of cases presenting with abdominal masses.
