Congenital Cystic Adenomatoid Malformation

A congenital cystic adenomatoid malformation (CCAM) is a benign (non-cancerous) mass of abnormal lung tissue usually located on one lobe (section) of the lung. CCAMs occur with equal frequency on both lungs. There are two major types of CCAMs:

  • Type I is distinguished by one or more large cysts (a closed sac that main contain air, fluids or semi-solid material).
  • Type II has both solid regions and cysts.

Here at Children’s Hospital Boston, we care for infants with CCAM in a special area of the hospital known as the Neonatal Intensive Care Unit (NICU). The NICU combines advanced technology and trained health care professionals to provide specialized care for the tiniest patients.
