Pseudoaneurysm due to cancer is uncommon generally and is extremely rare in lung cancer. We report two cases of false aneurysms due to lung cancer that spontaneously regressed upon chemotherapy without intervention. Both patients had squamous cell carcinoma of the lung and the diagnosis of a pseudoaneurysm was made using computed tomography. There was no evidence of severe bronchial hemorrhage and the pseudoaneurysms were small and well-encased. Chemotherapy was performed and the pseudoaneurysms resolved.
