Abstract
Esophageal leiomyoma is relatively rare disease, but can appears with a high uptake of fluorodeoxuglucose (FDG), a false-positive finding on a FDG PET/CT scan. A 64- year-old woman after a total thyroidectomy due to papillary and follicular carcinoma showed a high uptake of FDG in the distal esophagus on a subsequent FDG PET/ CT scan. The presence of an esophageal leiomyoma was suspicious from preoperative findings of endoscopic ultrasound and computed tomography, and an esophagectomy and proximal gastrectomy were performed, as the presence of a malignant lesion could not be excluded. As high uptake of FDG in the lesion on an FDG PET/CT scan corresponds to an esophageal cancer, an esophagectomy and proximal gastrectomy were performed and the lesion was confirmed as an esophageal leiomyoma after surgical biopsies. We report this case with a review of the relevant literature. (Korean J Gastrointest Endosc 2008;36:371-375)
