Pulmonary sequestration

Abstract

Pulmonary sequestration is a common cause of recurrent pneumonia in childhood. It represents 6% of all lung malformations, and most often affects the lower lobes. There are two types of sequestration - intralobar and extralobar. Children with lung sequestration present with recurrent lung problems in one and the same anatomical area. About 50% of lung lesions are intralobar and 60% of them are located in the left lower lobe. We present a case of an infant, MMB, 5 years old boy with history of protracted breathing problems and coughing. CT study shows pulmonary sequestration in segment #10 of the left lung, intralobar type. CT-angiography demonstrates blood supply of the sequestered section provided by a separate enlarged branch of the thoracic aorta. Because of his age the patient is referred to clinical follow-up, symptomatic therapy, and subsequent operative intervention until at least 8 months of age.
