Signalment:4-year-old castrated male French bulldog
History:ÊPresented to the referring veterinarian for lethargy, inappetance, abdominal discomfort (often after eating), vomiting, and diarrhea. At that time, a chemistry panel, barium swallow study, and fecal floatation were unremarkable. Clinical signs did not improve with empirical treatment, and 3.5 weeks later, the dog had lost approximately 15% of body weight. At that time, an abdominal ultrasound revealed diffuse circumferential thickening of the ileum up to 1.80 cm in diameter with a wall thickness of up to 0.91 cm with retention of the layered wall architecture.
Gross Lesions:The intestinal diameter ranges from 1.3 cm at the margin of the distal jejunum up to 3.5 cm along an approximately 17 cm long, thickened, firm portion of the ileum. The omentum is multifocally adherent to the ileal serosa. Within the thickened ileum, the intestinal wall is up to 8-9 mm thick with retention of wall layering and narrowing of the lumen. Within the ileal wall and along the serosa and adjacent mesenteric adipose are multifocal to coalescing, 4-10 mm diameter, firm, yellow-white nodules.
