68Ga-FAPI and 18F-PET/CT Images in Intestinal Tuberculosis.

Abstract: A 28-year-old woman presented with abdominal pain, bowel dysfunction, and weight loss for 3 months. 18F-FDG PET/CT revealed multiple hypermetabolic lesions in the intestines and peritoneal thickening/caking with moderate FDG activity. 68Ga-FAPI PET/CT showed intense FAPI uptake in the aforementioned FDG-avid lesions and a larger number of abnormal foci with intense FAPI uptake in the peritoneum than that shown in 18F-FDG images. Endoscopy-guided biopsy from the colonic mucosa was consistent with tuberculosis. The positive findings of 68Ga-FAPI in the current case highlighted that 68Ga-FAPI may have value in the evaluation of intestinal tuberculosis.
