Pulmonary sequestration: A rare case in a patient with acute chest pain and palpitation mimicking the acute coronary syndrome

Pulmonary sequestration (PS), a non‑functioning lung tissue, which lacks the normal communication with the tracheobronchial
tree and receives the blood supply from the systemic circulation, is a rare congenital malformation that comprises 0.5-6%
of all congenital pulmonary malformations. The presentation of PS with chest pain is very rare. In this article, we are aimed
to report the case of a patient with chief complaints of retrosternal chest pain and palpitation, which was suspected to be of
cardiac origin. Primary evaluations including exercise tolerance test, 48‑hour holter monitoring, coronary angiography ruled
out any cardiac problem. Further evaluations with Thoracic CT scan revealed a cystic mass in the retrocardiac region of
the lung. Thoracotomy surgery was done and the patient was finally diagnosed to be extralobar pulmonary sequestration
