title: [Congenital Bronchial Atresia Requiring Differentiation from Intralobar Sequestration].
abstract: We reported a case of bronchial atresia requiring differentiation from the intralobar sequestration. A 42-year-old man was referred to our institution with suspicion of intralobar sequestration, based on a 3-dimensional computed tomography (CT) angiography that showed abnormal blood vessels from the right inferior phrenic artery flowing into the right lower lobe. CT revealed a lesion between S9 and S10 wherein there were refluxed blood vessels from A9 without an accompanying bronchus, with polycysts and emphysematous changes. Ventilation-perfusion scintigraphy revealed a reduction in uptake in the same sites. He was diagnosed as congenital bronchial atresia preoperatively, and we performed a right basal segmentectomy. Pathological examination confirmed the bronchiectasis and emphysematous changes in the lung parenchyma, but malignant findings were not confirmed.
