SANCHO-HERNANDEZ, Rogelio et al. Extralobar pulmonary sequestration asymptomatic and the importance of diagnosis and perinatal treatment: Expectant management is not a therapeutic option. Neumol. cir. torax [online]. 2015, vol.74, n.4, pp.262-270. ISSN 0028-3746.

Introduction: Prenatal ultrasonography currently represents presentation form of bronchopulmonary malformations. To 90% manifest in neonates with obvious radiological abnormalities and symptomatic progression where surgical resection is clearly indicated. In < 4% causing mass effect with mediastinal shift, hydrops and fetal death and other extreme behave "asymptomatic" with apparent involution and its management has been controversial: early elective resection or radiologic expectant management to document the regression or development complications. It analyzes the literature about the controversy: operate or not to operate. Description of cases: Three fetuses with prenatal diagnosis of intrathoracic solid mass, asymptomatic newborns: one with hydrothorax and other without apparent prenatal involution both with abnormal irrigation compatible with extralobar sequestration, the third with a paracardiac mass where imaging studies did not diagnostic a extralobar sequestration of ectopic location and synchronous with cystic adenomatoid malformation, only transoperative and pathological findings confirmed the diagnosis. Discussion: In asymptomatic patients all bronchopulmonary malformations could be diagnosed and surgically resected for unrecognized their natural history and the low rate of natural regression, radiological proposals are not effective for monitoring.
