Pulmonary Sequestration: A Rare Case of Repeated Respiratory Tract Infection in Newborn and Adoloscence

Bronchopulmonary sequestration is a rare congenital anomaly which involves the lower respiratory tract in which there is a formation of aberrant lung tissue which has no communication with the bronchial tree or pulmonary arteries. It receives its blood supply from the systemic circulation i. e the thoracic and abdominal aorta in majority of the cases and from the subclavian, intercoastal, internal mammary, celiac, splenic or renal arteries in the remainder. Bronchopulmonary sequestration is cause of recurrent respiratory tract infection in newborn or adolescence. It has been broadly classified into intralobar and extralobar sequestration based on its relationship to the pleura, arterial supply and venous drainage. Here we present a 6 year old child with recurrent episode of respiratory tract infection. On imaging the chest X-ray showed a patch of consolidation in left paracardiac area and the patient was treated for pneumonia however on follow up the opacity persisted, then a CT scan was advised which clinched the diagnosis of intralobar sequestration and was operated thereby.
