Objective: To improve the early diagnosis and avoid preoperative misdiagnosis, we discuss some of the diagnostic problems related to thoracic saccular aneurysm rupture into the lung. Methods: A case report is presented. We report on a patient with rupture of aorta arch aneurysm into the lung with formation of pseudoaneurysm accompanied with left upper lobe atelectasis, who simultaneously underwent a left upper lobectomy, aneurysmectomy and aorta arch neoplasty. Results: The few cases described in the literature are reviewed to discuss the difficulties of differential diagnosis of left lung mass. The diagnosis methods and operation treatment of the aorta aneurysm are discussed. Conclusions: Angiography and CT are effective diagnostic methods of aorta aneurysm. These data suggest that it is an effective method of aneurysmectomy with/without left pneumonectomy or lobectomy to treat aneurysm of thoracic aorta.

Key Words: Aneurysm of thoracic aorta; Left lung; Operation
