Abstract:
A 67-year-old man had undergone thymectomy with partial resection of the left upper lobe and pericardium for thymic cancer. Four years later, he visited our hospital due to chest pain. Chest computed tomography revealed pneumopericardium. Nine months later, surgical treatment was performed due to the development of the left pneumothorax. Air leak was found from the bulla which was partially incarcerated into the pericardial space.
