title: [Intradiaphragmatic bronchopulmonary sequestration: a case report and review].
abstract: Bronchopulmonary sequestration is a rare congenital malformation, consisting in a mass of nonfunctioning lung tissue with no connection to the tracheobronchial tree. It can be classified into intra- and extra-lobar. Extra-lobar bronchopulmonary sequestration accounts for 25% of them; of these, only 1% are intra-diaphragmatic. There is little international literature about intra-diaphragmatic bronchopulmonary sequestration and its diagnosis and treatment remain a challenge for the surgeon. Our case is a newborn with antenatal diagnosis of an abdominal mass by ultrasound and magnetic resonance imaging (MRI) showing a left adrenal tumor that appeared to be a neuroblastoma. Postnatal computed tomography (CT) revealed the likelihood of an intra-diaphragmatic bronchopulmonary sequestration, although neuroblastoma could not be ruled out. Abdominal laparoscopy was performed in the bulging left hemidiaphragmatic area. A combined thoracoscopic approach was decided which showed that the defect was located in between both cavities. This is the first case of intra-diaphragmatic bronchopulmonary sequestration reported in Chile.
