INTRALOBAR pulmonary sequestration was described by Pryce as an anomalous artery running from the aorta in the vicinity of the diaphragm to the lung and a congenital bronchopulmonary sequestration or ectopia in the area of the lung served by the anomalous vessel.1 He classified the arterial anomaly into three types, in which the abnormal artery supplied only normal lung tissue, sequestrated lung alone, or both normal and sequestrated lung. The sequestration consists of bronchogenic cystic disease, which is described by Strode as cysts having walls composed of bronchial elements, viz., cartilage, elastic tissue, smooth muscle, and mucous glands.2 The lining consists of cuboidal or columnar epithelium, which is frequently ciliated. The contents of these cysts may be fluid, pus, blood, or air alone or in combination with the named fluid elements. The sequestrated portion usually has no communication with the normal bronchi and is thus not demonstrated in
