CCAM- Congenital Cycstic Adenomatoid Malformation

The lung normally develops as branches of the respiratory tree into distinct segments called lobes. When a segment of lung develops without the normal connections to the respiratory tree, a congenital cystic adenomatoid malformation (CCAM) can develop.

A CCAM can appear as a large cystic fluid-filled sac, or in some cases, can have multiple sacs and solid areas. Most lesions resolve spontaneously during pregnancy or remain small. In some cases, however, these masses may become so large that they interfere with blood return to the heart, cause fetal heart failure, or compress the normal lung tissue.

Therefore, fetuses with these types of lesions should be followed carefully. If the cyst enlarges or appears to be leading to heart failure, doctors may need to drain the cyst during pregnancy. Following birth, these babies require evaluation of their cysts and may ultimately need a surgical procedure to remove the CCAM or any remnants.
