Lung sequestration is a congenital disorder in which the lung parenchyma is not attached to the bronchial system, with blood supply originating from the aorta or various peripheral arteries. It may cause chronic pulmonary infection or bleeding and may require surgical resection. An 80-year-old male was incidentally found to have a paravertebral right thoracic mass. Computed tomography scan with contrast suggested a feeding vessel from the supraceliac aorta and suspicion of a lung sequestration was confirmed on selective angiography. He developed chronic cough, but this was managed symptomatically and no specific treatment, such as surgical resection, was necessary. Lung sequestration in the elderly is a rare condition but should be considered in a patient presenting with stable lung lesions, especially if a feeding artery from the aorta can be identified.
