Bronchial atresia Bronchial atresia is a congenital abnormality resulting from interruption of a bronchus with associated peripheral mucus impaction and associated hyperinflation of the obstructed lung (10). The hyperinflation of the affected lungsegment is caused by collateral ventilation through the pores of Kohn. The characteristic finding is a hyperlucent area of the lung surrounding a branching or nodular opacity that extends from the hilum. Notice the central mass surrounded by hyperlucent lung (blue arrow). #Clinical #Radiology #CXR #BronchialAtresia #Bronchial #Atresia #RadiologyAssistant
