18F-NaF PET/CT Finding in a Patient With Abdominal Discomfort After Schistosomiasis

A 77-year-old man with back pain and abdominal distention underwent 18F-NaF PET/CT examination to evaluate potential bone lesions. Multiple foci of increased activity were noted in the chest, which corresponded to bilateral ribs and suggested possible occult fractures. Surprisingly, increased 18F-NaF uptake was observed in the region of pelvis, which corresponded to calcification along the colon wall, a sequela of intestinal Japanese schistosomiasis that the patient experienced 30 years ago.
