2004 Radiology Exam - Abdomen Case 1

Objective of the Case
To recognize and describe the radiographic features of a small intestinal obstruction.

Information Provided to Candidate
Eight-year-old neutered male Shar-Pei presented for vomiting and bloody diarrhea of one week duration. See images below. Click to enlarge.

Findings Expected from Candidate
The candidates were expected to recognize the presence of gas and fluid distended small bowel indicative of a distal small intestinal obstruction. A secondary finding is moderate gas and fluid/ingesta distension of the stomach.

Conclusion Expected from the Candidate
An appropriate differential diagnosis would include intussusception, foreign body, intestinal neoplasia and stricture. Functional causes of obstruction would be less likely due to the segmental nature of the small bowel distention.
