Epiphrenic diverticulum(traction type) is such a rare disease. The case of this disease which is due to mediastinal tumor, not because of inflammatory adhesion or of motor disorder is especially hard to find. The patient was a 50-year-old male and admitted with the intermittent postprandial chest discomfort. The chest CT and esophagography showed epiphrenic diverticulum(traction type). The tumor was located at the left anterolateral of thoracic spine, adhered to the right wall of esophagus. We performed the diverticulectomy and extirpation of mediastinal tumor under left posterolateral thoracotomy. The tumor and the esophagus were well seperated without invasion to the esophagus. In the pathology of resected tissues, solitary neurofibroma was diagnosed. There was no complication or recurrence after surgical resection.
