A case with unusual localized thymoma was resected completely by uniportal video assisted thoracic surgery

Abstract

Thymoma is a rare tumor usually localized anterior mediastinum. We herein reported a case with thymoma localized paracardiac area that was resected completely by uniportal video assisted thoracic surgery (VATS). In thorax tomography of the patient referring chest pain, limited well lesion was localized at right paracardiac region which pushed the lung parenchyma. The size of lesion that was in the anterior mediastinum adjacent to the right atrium was approximately 50x33 mm and its average density was 52 HU. We performed VATS. The lesion was removed en bloc using by single port disection. The radiological differential diagnosis of the lesion was considered bronchogenic cysts and pericardial cysts, and was reported as type AB thymoma by pathologists. Thymomas are commonly observed anterior mediastinum. The diagnosis of atypical localization of thymomas is usually difficult. Hence increasing use of VATS provides minimally invasive diagnosis and treatment of mediastinal mass. Pam Med J 2016;9(2):167-169
