INTRATHORACIC LIPOMA ARISING FROM RETROPERITONEAL FATTY TISSUE: CASE REPORT

There was found abnormal shadow at the right paracardiac zone on a 67-year-old man patient's chest radiograph which was taken incidentally. Computed tomography (CT) scan revealed a homogeneous mass of fatty density at the right hemithorax extended into the retroperitoneal space through the foramen of Bochdalek. The tumor, 15 x 10 x 5 cm in size, was extended into the retroperitoneal space and caried off completely with limited thoracotomy. Histopathologically the tumor was diagnosed as a mature lipoma. This tumor was considered to originated from the retroperitoneal fatty tissue and to herniate into the posterior mediastinum through the foramen of Bochdalek. The case is presented because of its rare occurrence in the mediastinum.
