Pulmonary sequestration is an abnormal lung tissue that does not communicate with tracheobronchial tree, and that receives blood supply from anomalous arteries. Pulmonary sequestration is divided into two anatomical forms, intralobar and extralobar. Extralobar pulmonary sequestration is usually located between the diaphragm and the lower lobe and has systemic arterial supply and venous drainage, and most patients are diagnosed in their infancy. We report an extralobar pulmonary sequestration located between the right upper lobe and the lower lobe in a 48-year-old female adult, which has anomalous blood supply from the right pulmonary artery and venous drainage directly into the left atrium.

Congenital cystic adenomatoid malformation and Extralobar Pulmonary sequestration are very rare congenital anomalies. We experienced a 4 year-old female patient who had Congenital cystic adenomatoid malformation in her lower lobe of left lung. We accidently found extralobar pulmonary sequestration associated with Congenital cystic adenomatoid malformation at operation field. The resection of the left lower lobe and the extralobar pulmonary sequestration were performed. The arterial supply of the extralobar pulmonary sequestration was one anomalous artery arised from the thoracic aorta. The Venous drainage of expralobar pulmonary sequestration was intercostal vein into the azygous vein. The patient was discharged without any problem.

Congenital pleural effusions are uncommon. The majority of cases are due to chylothorax, hydrops fetalis, and infection. Effusions of this nature are, for the most part, self-limited. We experienced a rare case of a congenital unilateral pleural effusion due to an extralobar sequestraion with pulmonary lymphangiectasia. Pleural effusion was found by antenatal ultrasonography and confirmed by CT scans and CT angiography of the chest in the neonatal period. The patient underwent an open thoracotomy where extralobar sequestraion located between the diaphragm and the left lower lobe was removed. His postoperative course was uncomplicated and there was complete resolution of the pleural effusion.

Background: Pulmonary sequestration is not common and it's diagnosis needs special care such as an aortogram ar tomography. Material and Method: We have experienced 13 patients who had pulmonary sequestration from January 1990 to September 1997. Result: Six men and seven women were treated and their mean age was 25.8±14.3 years. Their chief complaints were coughing, chest pain, and no symptoms in decreasing order. There were nine intralobar(ILS) and three extralobar(ELS) pulmonary sequestrations and one patient had both. There was no preference in location of either left or right. They were mainly diagnosed by aortography and their feeding arteries commonly originated from the lower thoracic aorta. The patients with ILS were treated by lobectomy and those with ELS by sequestrectomy. Conclusion: to treat pulmonary sequestration properhy, aortogram or chest CT is warranted to iidenty the abnormal origin of feeding artery.

This is a case report of extralobar pulmonary sequestration with bronchogenic cyst located in aorto-pulmonary window area of left thorax in a 17 months old male patient. In this case, a bronchogenic cyst was presented immediately adjacent to the extralobar pulmonary sequestration. Communication between the extralobar pulmonary sequestration and bronchogenic cyst was not seen grossly or microscopically. The lesion was simply excised and the postoperatively course was uneventful.

Pulmonary sequestration and congenital cystic adenomatoid malformation are two infrequent congenital pulmonary diseases and the combination of these two entities is rare. We had experienced a 3 week old male patient with a pulmonary mass, who had been sufyerring from tachypnea and chest wall retraction after birth. The pulmonary mass was suspected as a congenital cystic adenomat id malformation by chest CT. And therefore, we performed urgent operation via standard thoracotomy incision. Upon a thoracotomy, there was an extrapleural mass with anomalous blood supply near the posterior diaphragm and multiple cystic lesions in right lower lobe. The two anomalous arteries arising from the thoracic aorta and one vein draining into the azygos vein were ligated. and then the extrapleural mass was removed and a right lower lobectomy was performed. Final histologic diagnosis was congenital cystic adenomatoid malformation associated with extralobar pulmonary sequestration. The patient was discharged without any problem.

Pulmonary sequestration is an unusual congenital malformation characterized by the presence of nonfunctioning lung tissue which usually has no communication with the normal bronchial tree and receives its blood supply from an anomalous systemic artery. Extralobar form is a very rare congenital malformation. We have experienced a 54 year old female patient with a mass in the upper lobe complaining of cough and blood tinged sputum. A triangular shaped mass was located in the left upper lobe, medially. The arterial blood supply were from the thoracic aorta and the pulmonary artery but there was no the tracheobronchial communication. The venous drainage was through the pulmonary vein. The mass was confirmed as extralobar pulmonary sequestration associated with a pericardial defect.

Pulmonary sequestration is an uncommon congenital pulmonary malformations characterized by presence of nonfunctioning lung tissue which receives its blood supply mostly from the anomalous systemic arteries. We have experienced a 30 year old male patient with a mediastinal mass complaining of intermittent chest pain, and the mass was histologically confirmed as extralobar pulmonary sequestration. The anomalous blood supply origined from the right pulmonary artery but there was no communication with the tracheobronchial tree. He underwent operation through midsternotomy incision for the purpose of concurrent resection of enlarged thymus noted on chest CT.

Pulmonary sequestration is an unusual congenital malformation characterized by the presence of nonfunctioning lung tissue which usually has no communication with the normal bronchial tree and receives its blood supply from an anomalous systemic artery. We present a case of extralobar pulmonary sequestration experienced recently. The patient was 13 month old female with a complaint of fever, coughing and tachypnea. Chest film showed large homogeneous opacity in left lower lung field. At operation, a homogeneous mass was located between the left upper lobe and lower lobe, measuring 4X6X5cm in dimension. The aberrant artery was originated from the descending thoracic aorta, 1 cm in length and 3 mm in diameter. After division and ligation of the aberrant artery, sequestrectomy and lingular segmentectomy was done due to abscess formation. The postoperative course was smooth. She was discharged on postoperative thirteenth day.

Background : Pulmonary sequestration is a rare congenital malformation, which is manifested by formation of nonfunctioning lung tissue lacking normal communication with the tracheobronchial tree. The preoperative diagnostic rate has been relatively low, and without consideration of pulmonary sequestration, unexpected bleeding from aberrant vessels may be a serious problem during the operation. The purpose of our study is to describe the clinical features of pulmonary sequestration based on a review of 15 cases treated by operation. Method : Fifteen patients with pulmonary sequestration who had undergone surgical treatment from 1991 through May 1996 at Yongdong Severance Hospital and Severance Hospital were reviewed retrospectively. Results : The mean age of the patients was 22.5 years (range 5~57), and male to female ratio was 9 : 6. Clinical presentations varied from recurrent respiratory infections such as fever, cough, and sputum or chest pain to no symptom. The chest simple X-rays showed multicystic shadow(10/15) and solid mass-like shadow(5/15). The chest CT scans, done in twelve cases, showed multicystic lesion with or without lung infiltration(8/12), solid mass-like lesion(4/12), The chest MRIs, done in three cases, revealed the aberrant arteries originating from descending aorta(2/3). Aortograms, done in four cases, showed the aberrant arteries originating from descending thoracic aorta(2/4), abdominal aorta(I/4), and intercostal artery(1/4). and the venous returns were via the pulmonary veins. Pulmonary sequestration was considered preoperatively in six patients of fifteen. Other preliminary diagnosis were lung tumor(3/15), lung abscess(21/15), bronchiectasis(2/15), and mediastinal tumor(2/15). In the operative findings, twelve cases were of intralobar type and three cases of extralobar type. The left lower lobe was most often affected(9/15) and one extralobar sequestration was in the pericardium. The aberrant arteries originated from descending thoracic aorta(6/15), abdominal aorta(1/15), internal thoracic arteries (2/15), intercostal artery(1/15), pericardiophrenic artery(1/15), but in four cases, the origins could not be defined. There was no mortality or complication postoperatively. Conclusion : In our study, preoperative diagnostic rate was relatively low, and clinical features were similar to previous reports. Preoperative vigorous diagnostic approach including aortography is strongly advocated not only for its diagnostic value, but also for accurate localization of the aberrant vessels, which is major concern to surgical procedure.
