“…Discussion BPS is a rare congenital anomaly that accounts for 0.15∼6.4% of congenital pulmonary malformations 2 and 1.1∼1.8% of pulmonary resections 3 . Among the two types of BPS, intralobar BPS is more common, representing approximately 75∼90% of BPS 2,7 .…”

“…Intralobar BPS does not have their own pleural covering, as they are located on a normal lobe and share pleura with the normal lung tissues. Extralobar BPS has a separate lining of pleura, because they are located outside the normal lung [2][3][4][5] . Intralobar sequestration is typically diagnosed in pediatric or adolescent patients, with equal gender prevalence.…”

Bronchopulmonary Sequestration with Dual Arterial Supply from Celiac Artery and Thoracic Aorta

Bronchopulmonary sequestration (BPS) is a rare congenital malformation of the lower respiratory tract. Most intralobar BPSs are provided with an arterial blood via the thoracic or abdominal aorta but such a supply is rarely found in patients older than 50 years. We report a case of an intralobar BPS with a dual arterial supply from the celiac artery and thoracic aorta in a 50-year-old man presenting with a respiratory tract infection and haemoptysis. To our knowledge, this is the first case report of a BPS supplied by the celiac artery and thoracic aorta in a 50-year-old man.

“…If the accessory lung bud arises early in embryonic life before development of the pleura, an intralobar sequestration (ILS) will be formed; if the accessory bud arises after the pleura has developed, an extralobar sequestration (ELS) will be the result. [2][3][4] Twelve to 25% of the pulmonary sequestrations are extralobar 1,4 and can be located above or below the diaphragm. ELS are found in 90% of the cases above the diaphragm and 10% are subdiaphragmatic.…”

“…ELS are associated in 40% to 60% of the cases with other congenital malformations. 1,6,7 Concurrent malformation affecting the lungs and the gastrointestinal system prompted Gerle and colleagues 2 to propose a unifying etiologic concept to this abnormal development of the foregut with the term of congenital bronchopulmonary foregut malformation 2,6 to include the accessory lung tissue, whether intralobar or extraolobar in location, with or without communication with the esophagus or stomach.…”

A one-year-old boy presented with a left retroperitoneal subdiaphragmatic mass accidentally discovered during admission for bronchopneumonia. The clinical impression was neuroblastoma. Histologically, the mass revealed pulmonary sequestration with cystic adenomatoid pattern associated with severe granulomatous epithelioid necrotizing inflammation simulating tuberculous infection.Pulmonary sequestration represents 1.1% to 6.8% of lung malformations. 1 It consists of a cystic or solid mass of nonfunctioning lung tissue. Such pulmonary tissue does not communicate with the tracheobronchial tree and in most cases retains its systemic arterial supply.Sequestration may occur within the normal lung tissue (intralobar) or outside the normal lung (extralobar). The anterior portion of the endodermis or foregut is considered to be the origin of the esophagus and the lungs. If the accessory lung bud arises early in embryonic life before development of the pleura, an intralobar sequestration (ILS) will be formed; if the accessory bud arises after the pleura has developed, an extralobar sequestration (ELS) will be the result. [2][3][4] Twelve to 25% of the pulmonary sequestrations are extralobar 1,4 and can be located above or below the diaphragm. ELS are found in 90% of the cases above the diaphragm and 10% are subdiaphragmatic. ELS are associated in 40% to 60% of the cases with other congenital malformations.

Clinical History.\p=m-\A3,450-gm boy was born after a full-term pregnancy. The Apgar score was 10 at one minute, and no abnormality was detected on physical examination. The postnatal course of four days in the nursery was uneventful.The infant was admitted to the hospital at the age of 3 weeks with a history of diarrhea and vomiting of three days' duration. Physical examination findings disclosed a well-nourished infant weighing 3,850 gm; a temperature of 36.7 C; pulse, 124 beats per minute; and respirations, 64 breaths per minute. There was no cyanosis, anemia, or edema. The chest was symmetrical in shape, but substernal retractions were noted with inspiration. Clinically, the lungs appeared to be normal, and there was no shift of the mediastinum. The heart sounds were normal, and peripheral pulses were present normally. Blood pressure in the extremities by the flush method was, right arm and left arm, 70 mm Hg; right leg and left leg, 60 mm Hg. A grade 2/6 ejection sys¬ tolic murmur was heard over the lower half of the sternum and over Fig 2.Fig 3.the posterior chest below the right scapula; the murmur was louder at the back. The liver was felt 3 cm be¬ low the costal margin; the spleen was not palpable.Physical Examination.-Results of complete blood cell count, sweat ion¬ tophoresis, and immunoglobulin as¬ say were within normal limits, and throat and nasopharyngeal cultures grew normal flora. Roentgenograms of the chest are shown below (Fig 1, left and right). Electrocardiogram and results of barium sulfate swallow were normal. A ten-day course of am¬ picillin was given intramuscularly, but no change was seen in the chest roentgenogram.
