Bronchopulmonary sequestration

Bronchopulmonary sequestration is a rare lesion making up less than 10% of all congenital pulmonary malformations. The two classic types, extralobar and intralobar, can be distinguished by whether or not the sequestered pulmonary tissue is enclosed by a separate visceral pleural lining. A case of intralobar bronchopulmonary sequestration is presented. At present, aortography is necessary to establish the diagnosis, but other imaging modalities including computed tomography, ultrasound, and magnetic resonance imaging offer the potential for additional useful information.
