Intralobar Pulmonary Sequestration with 3 Aberrant Arteries in a 2-Year-Old Boy

Pulmonary sequestration is a rare congenital pulmonary malformation. This malformation consists of dysplastic lung tissue with no connection to the tracheobronchial tree and with an anomalous systemic arterial supply. The clinical hallmarks of intralobar sequestration are recurrent pulmonary infections. Chest CT scan with contrast is actually gold standard for identifying pulmonary sequestration. CT volume-rendering technique image reconstructions can be particularly helpful in detecting anomalous arterial vessels and show the venous drainage. Surgical resection is the treatment of choice and intralobar sequestration often requires lobectomy. We present an interesting case of intralobar pulmonary sequestration with 3 aberrant arteries arising from the descending thoracic aorta in a 2-year-old boy.
