A rare cause of recurrent chest infection in children-bronchopulmonary sequestration.

Bronchopulmonary sequestration is one of the rare thoracic congenital anomalies. We report the case of a 6 year old boy with history of recurrent episodes of chest infection and breathing difficulty. This time admitted with fever and cough. Investigations revelaed neutrophilic leucocytosis, raised C-reactive protein and a retrocardiac opacity on chest radiographs. Contrast enhanced Computed Topography(CT scan) revealed a large, well defined, left lower lobe multi-loculated cystic mass with a vessel arising from the descending aorta supplying sequestrated lung portion. These CT scan findings were suggestive of diagnosis of an intralobar bronchopulmonary sequestration (IPS). Surgical resection of this opacity was done and histopathology report confirmed the diagnosis of bronchopulmonary sequestration.
