Ultrasonographic diagnosis--small bowel lymphangiectasia in a dog

A 7-year-old, West Highland White Terrier had a 5-month history of diarrhea, dysorexia, and weight loss. Sonographically, there was a focal area of intestinal thickening with loss of layering. A neoplastic or severe inflammatory condition was suspected and intestinal lymphangiectasia was diagnosed histopathologically. This patient seems to be the first description of intestinal lymphangiectasia appearing as an intestinal mass.
