Esophageal diverticulum is a disease that occurs mainly in adults. According to its location, it is named as pharyngoesophageal, paratracheal and epiphrenic diverticulum. Epiphrenic diverticulum is especially accompanied with esophageal leiomyoma sometimes. In this case. esophageal leiomyoma is combined with suhphrenic diverticulum. The authors present the case with review of literature. The diagnosis of subphrenic diverticulum was confirmed by esophagogastroscopy with biopsy, esophagogram and abdominal CT. Postoperative fin- dings showed it to be accompanied with esophageal leiomyoma.
