Lipogranulomatous lymphangitis in canine intestinal lymphangiectasia

Lipogranulomatous lymphangitis of the intestine occurred in four dogs with intestinal lymphangiectasia. All four presented with chronic diarrhea; three had ascites and two had hypoalbuminemia. Lipogranulomas appeared in lymphatics, often at the point of mesenteric attachment, of small intestine, ileum, or ileum and colon. Mesenteric lymphatics were obstructed and villous lacteals were distended. Mesenteric lymph nodes of one dog contained large lipid spaces and that same animal had a solitary subcapsular lipogranuloma of the liver. This disorder is one of several that result in protein-losing enteropathy in dogs.
