Abstract

The purpose of the present study was to retrospectively evaluate the nature and significance of unexpected focal 18-FDG uptake localized by PET/CT within the intestinal tract.

METHODS:

The data of 4,033 PET/CT were retrospectively reviewed. One hundred and eighty PET/CT showed unexpected focal uptakes (patients with known intestinal neoplasia were excluded). Among them, 42 patients corresponding to 47 focal uptake sites were investigated by endoscopy or surgery.

RESULTS:

Height endoscopy results were negative (17%). We found 25 adenomatous polyps (53.2%), 10 neoplasms (21.3%) and 4 inflammatory lesions (8.5%). 18-FDG uptake values were not statistically different between the 4 groups.

CONCLUSION:

Eighty-three percent of unexpected intestinal foci of hypermetabolism are either inflammatory, malignant or premalignant lesions. These results justify systematic investigation of these lesions.
