In Utero Diagnosis of Unilateral Bronchial Atresia: One Pathologically Proven and 2 Presumed Cases With Similar Sonographic Findings at Presentation.

ABSTRACT

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.
