[size=20px]A 3 month-old term infant was diagnosed prenatally with a congenital lung lesion. She had no respiratory issues postnatally and remains well.

B

correct answer

B Macrocystic lung lesion

​

Large, macrocystic congenital lung lesions are more likely to be malignant than those that are microcystic. Lesions that are small, asymptomatic, detected prenatally, or have a feeding vessel are more likely to be benign.
