“…Congenital high airway obstruction syndrome has a sonographic appearance that is rather unique to the diagnosis. In contrast, the sonographic appearance of unilateral bronchial atresia with massive enlargement of only one lung may mimic more commonly encountered unilateral fetal lung abnormalities, specifically microcystic (type 3) CPAM or pulmonary sequestration 1 , 9 . In fact, all 3 of the cases reported here were originally diagnosed as CPAM at the outside referring institutions.…”

It is important to distinguish, if possible, these entities by in utero imaging, for the clinical course, treatment options, and outcomes, because unilateral bronchial atresia and CPAM differ.…”

Unilateral bronchial atresia is a rare prenatal diagnosis that can be confused with other congenital lung abnormalities, particularly congenital pulmonary airway malformation. Accurate distinction between these entities is important for appropriate clinical care and prognosis. Familiarity of the key imaging and clinical features of unilateral bronchial atresia in comparison to other fetal lung abnormalities should increase the likelihood of achieving a timely and accurate diagnosis.

“…Esta imagen de zonas hipoventiladas puede confundirse con el pulmón poco aireado de recién nacidos con escaso clearence de líquido pulmonar en las primeras horas de vida, razón por la cual muchos autores recomiendan evitar una evaluación radiológica inmediata luego del parto (16). Imágenes de tomografía axial computada y reconstrucciones 3D pueden también ser útiles en su diagnóstico (16,18). (Figura 1).…”

RESUMENLas malformaciones pulmonares congénitas son un grupo heterogéneo de alteraciones del desarrollo pulmonar que pueden producirse en distintas etapas de la embriogénesis, afectando al parénquima, la irrigación arterial, al drenaje venoso o ser una combinación de ellas. La nomenclatura y clasificación se ha modificado con frecuencia en el último tiempo, por lo que conocer la fisiopatología y etapa del desarrollo en que se producen es lo más relevante para su entendimiento. El diagnóstico prenatal se hace en base a la ecografía y se apoya con resonancia magnética fetal, mientras que la radiografía y la TAC pulmonar son las principales herramientas para el diagnóstico posnatal. La presentación clínica es variable, desde la muerte por hidrops fetal, hasta pacientes que permanecen asintomáticos por años. Existen alternativas terapéuticas prenatales para pacientes con alto riesgo de mortalidad intrauterina, y la extirpación posnatal es la conducta con más respaldo incluso en pacientes asintomáticos.Palabras clave: Malformación pulmonar congénita, malformación adenomatoidea quística, malformación congénita de la vía aérea pulmonar, secuestro pulmonar, enfisema lobar congénito. SUMMARYCongenital lung malformations are a heterogeneous group of disorders of lung development that may occur at different stages of embryogenesis, affecting the parenchyma, arterial supply, venous drainage or a combination of them. The nomenclature and classification has been changed frequently in recent times, so knowing the pathophysiology and stage of development in which they occur is the most relevant for understanding. Prenatal diagnosis is based on ultrasound and fetal MRI, while pulmonary radiography and CT are the main test for post-natal diagnosis. The clinical presentation is variable, from fetal hydrops death, to patients who remain asymptomatic for years. There are prenatal treatment options for patients at high risk of intrauterine mortality, and the postnatal removal is the behavior with more support, even in asymptomatic patients.
