Bilateral pulmonary sequestration in the elderly adult

Pulmonary sequestration (PS) is a rare malformation consisting of aberrant lung tissue which is not affiliated with the normal bronchial system and is fed by an aberrant artery that derives from systemic arteries. However, PS is usually seen unilaterally but, only rarely, it is bilateral. Most patients with PS are diagnosed because of symptoms due to pulmonary infection or cardiac disease, while a small portion of patients are asymptomatic and diagnosed incidentally. In this report, we present an extremely rare case of asymptomatic bilateral PS which was diagnosed at advanced age. To our knowledge, this case represents the oldest patient in the literature, and the second case that was diagnosed in a patient over the age of 50.
