What's Your Diagnosis?: 1.5 yr old German Shepherd with chronic diarrhea (An Unusual Diagnosis!)


History and Physical Examination:

Michael is a 1 1/2 year old male castrated German Shepherd presented with a history of bloody diarrhea for 2 weeks. Frank blood has been noted in the stool. On physical examination, a mid-abdominal, movable tubular mass was palpated. Pain was elicited on palpation.  Fecal examination revealed whipworms.


Review the plain film lateral abdominal radiograph and upper gastrointestinal barium series (Fig 1-2). (The ventro-dorsal projections were not contributory.)

A ventral midline exploratory laparotomy was performed, and the ileo-ceco-colic region was exposed. (Fig. 3: Ileum to the right, colon to the left)

A colotomy was performed on the antimesenteric aspect of the proximal colon and a structure was extruded from the colonic lumen. (Fig. 4)
