Diffusely increased colonic F-18 FDG uptake in acute enterocolitis

Abstract

A 60-year-old woman with 8 remote history of colon carcinoma was studied with F-18 FDG PET imaging 5 days after admission for saute toxigenic enterocolitis. Marked end diffusely increased uptake was noticed throughout the ascending and transverse colon, which was noticed to be edematous and thickened on contrast CT examination. The study emphasizes the need to consider nonneoplastic entitles, such as enterocolitis in the differential diagnosis of intensely hypermetabolic colonic lesions on F-18 FDG PET examinations.
