6 month old Cairn Terrier

April 13, 2015 By Allison Zwingenberger

Today’s case is a 6 month old male neutered Cairn Terrier with 3 days of vomiting and diarrhea, and progressive lethargy.

Findings

There are markedly dilated bowel loops in the caudal portion of the abdomen. More normal sized loops are gas-filled in the cranial abdomen. The peritoneal detail is poor, likely because of his young age.

Differential Diagnosis

Mechanical obstruction – foreign body, intussusception.

Diagnosis

Jejunal-jejunal intussusception.

Discussion

Intussusceptions are common in young dogs secondary to intestinal hypermotility. The bowel “telescopes” on itself causing a mechanical obstruction, or partial obstruction. Most intussusceptions involve the ileum and colon. It is more rare to see a jejunal intussusception. The radiographic findings fit with the diagnosis. A more proximal obstruction results in focal bowel dilation, as seen in this case. Distal obstruction, such as in a usual intussusception, often causes dilation of the entire proximal or oral small intestine.

Ultrasonography diagnosed the intussusception. You can see the “bowel within bowel”, or concentric rings of intestine in both the longitudinal and the cross-sectional image. There is often mesenteric fat pulled into the intussusception, which appears hyperechoic on the transverse image.

    There is a soft tissue mass effect on the caudal abdomen, displacing part of the small intestine cranially. Bladder limits are unclear. The location of this mass would suggest enlarged bladder, but age and history leads to GI problems. I would think of severe torsion/intussusception inflammatory procces of the distal part of small intestine but ultrassound would be required to discard lower urinary tract issues.
