Abstract—Pulmonary sequestration is a rare congenital malformation characterized by a mass of non- functioning lung tissue separated from the normal bronchopulmonary tree and vascularized by an aberrant systemic artery. While working on the fissures and lobes of the 60 lungs we observed the presence of lung tissue within the pulmonary ligament. These were pulmonary sequestrations or lower accessory lobes. This was observed in 6 specimens (10%) out of 60 lungs and all the 6 cases were on the left side. Clinically, the malformation remains generally silent as long as there is no secondary infection or communication with the bronchial tree or gastrointestinal tract. It can be diagnosed by aortography and MRI angiography. Accessory pulmonary tissue has a tendency to become cystic and is thus a source of congenital cysts of the lungs. The most significant complications were pleural empyema, haemothorax and haemopneumoperitoneum in case of extralobar sequestration. Resection of the involved lung segments lead to excellent results and is highly favorable.
