Most congenital lung anomalies are discovered in utero, often at the early 2nd trimester US screening, this may be followed by a prenatal MR for more detailed characterization. Many “mass-like” lesions decrease in size and conspicuity during the 3rd trimester and are asymptomatic and not visible or missed with only subtle changes on a postnatal chest radiograph. A 3–6-month postnatal CT or MR scan is often obtained to visualize the lesion and evaluate its features, size and extent and decide on surgical or conservative management. Lesions that are not diagnosed prenatally, dismissed or forgotten because of a normal appearing neonatal CXR or are managed conservatively or with partial surgical treatment (e.g. multiple lesions or incomplete resection) may be seen later in life either incidentally, in follow-up or with associated complications such as infection. Additionally, there are several acquired entities that can mimic or be mistaken for congenital lung anomalies. This poster will review and illustrate the late presentation of multiple congenital lung lesions beyond the neonatal period including bronchogenic cyst, lobar/segmental bronchial atresia and overinflation, CPAM, sequestration and hybrid CPAM/sequestration, several with clinical symptoms/complications as well as residual post-surgical lesions. Mimics of congenital lung lesions illustrated will include infectious acquired lobar overinflation, mediastinal lesion compressing airway causing lung/lobar overinflation and pneumonia with pneumatoceles mimicking infected CPAM.
