Stercoral colitis, caused by fecal impaction, can lead to severe complications. This case highlights incidental FDG PET/CT findings of stercoral colitis in the rectum during cancer staging.
Area of Science:
- Gastroenterology
- Radiology
- Nuclear Medicine
Background:
- Stercoral colitis is a rare inflammatory condition resulting from fecal impaction.
- Untreated, it can cause severe complications like bowel perforation, peritonitis, and septic shock.
Purpose of the Study:
- To describe the FDG PET/CT findings of stercoral colitis.
- To highlight the incidental detection of stercoral colitis during staging for other conditions.
Main Methods:
- Case report describing findings in a single patient.
- Utilized 2-deoxy-2-[18F]fluoro-D-glucose (FDG) Positron Emission Tomography/Computed Tomography (PET/CT).
Main Results:
- FDG PET/CT revealed fecal impaction within a dilated rectum.
- Asymmetrical rectal wall thickening and perirectal fat stranding were observed.
- Diffusely inhomogeneous FDG activity was noted in the rectal wall and surrounding edematous areas.
Conclusions:
- FDG PET/CT can incidentally detect stercoral colitis.
- Imaging findings include rectal wall thickening, fat stranding, and abnormal FDG uptake.
- Early recognition of these findings is crucial for timely intervention and preventing fatal outcomes.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
