Abstract
We report the case of a 35-year-old male patient who complained of abdominal pain for 3 months. Both 18F-FDG PET/CT and abdomino-pelvic PET/MR revealed thickened intestinal wall in the pelvic group with elevated FDG uptake, which was misdiagnosed as malignant intestinal lesion. To our surprise, the lesion was histologically confirmed to be a small intestinal hemangioma with chronic ulcer and intussusception. Small intestinal hemangiomas are very rare benign tumors of the gastrointestinal tract and may lead to eventual misdiagnosis when the tumor and lymph nodes show a malignant sign of high FDG uptake, which should be noted by nuclear medicine physicians.
