Abstract
A 38-year-old man with chest discomfort was admitted to our hospital. A chest radiograph and computed tomography showed the posterior mediastinal tumor surrounding the lower esophagus. FDG-PET showed high-level FDG accumulation in the tumor with a standardized uptake value max of 5.80, suggesting malignancy. We performed tumor biopsy by video-assisted thoracoscopic surgery for a diagnosis. The tumor was pathologically diagnosed as an esophageal leiomyoma.
