Congenital masses of the lung are a spectrum of interrelated abnormalities
that includes congenital lobar overinflation, bronchogenic cyst, congenital
cystic adenomatoid malformation (CCAM) and sequestration. The prenatal and
postnatal imaging features of these lesions are reviewed, emphasizing the
importance of serial prenatal sonograms and postnatal imaging studies, incl
uding radiography and computed tomography. Masses that become inconspicuous
, or disappear on serial prenatal sonograms are discussed, as well as the i
mportance of postnatal imaging studies in the evaluation of these lesions.
Finally, the management of congenital masses of the lung is reviewed, empha
sizing the importance of imaging studies in the preoperative evaluation.
