title: Lung cancer mimicking aortic dissecting aneurysm in a patient with situs inversus totalis.
abstract: Lung cancer and situs inversus totalis are two completely irrelevant conditions. The likelihood of both conditions occurring simultaneously in one person is very rare. We report here a case of a 50-year-old man who presented with intermittent chest pain. Enhanced computed tomography of the chest showed situs inversus totalis and a round mediastinal mass embracing the thoracic aorta. The primary diagnosis was suggested as pseudo aortic dissecting aneurysm. However, a tumor in the right lower lung was discovered during surgery, which enclosed and invaded the thoracic aorta. Finally, the patient successfully underwent right lower lobectomy accompanied by lymph node excision and partial replacement of the thoracic aorta with an artificial vascular graft under cardio-pulmonary bypass.
