[Management of a lung tumor accompanied by aortic dissection; report of a case].

: During an annual health check-up, a 75-year-old man was admitted to our hospital due to an abnormal shadow in the left upper lung field. A computed tomography (CT) scan taken at his 1st hospital visit showed a calcified nodule in the left upper lobe and Stanford type A aortic dissection. We could not perform bronchofiberscopy due to the risk associated with the aortic dissection and could not make a diagnosis prior to surgery. Because of the possibility of lung cancer, surgery for the lung tumor and aortic dissection was performed. The pathological diagnosis of the lung tumor was a hematoma. In a case of suspicion of lung cancer along with cardiovascular disease, a surgical diagnosis might be considered.
