ABSTRACT
Duodenal leiomyomas are rare benign tumors of mesenchymal origin. Generally, Fluorodeoxyglucose (FDG)-PET would have a negative finding in leiomyomas. A 52-year-old man was referred to our hospital with melena. Gastroendoscopy revealed the presence of a huge submucosal tumor with ulceration at the duodenum bulb. Subsequent CT demonstrated a poorly enhanced oval mass adjoining the duodenal bulb. FDG-PET scan demonstrated an excessive accumulation of FDG in the lesion. A definitive diagnosis of duodenal leiomyoma was made on the basis of the pathologic finding of his surgical specimen. We report in this first case that duodenal leiomyma may show a potential pitfall of giving a positive FDG-PET result. Through this case, we would like to caution clinicians against PET-dependent evaluations of malignant potential of duodenal submucosal tumors.
