What is cystic adenomatoid malformation?

Congenital cystic adenomatoid malformation (CCAM) is a benign lung lesion that appears before birth as a cyst or mass in the chest. It is made up of abnormal lung tissue that does not function properly, but continues to grow.

What are complications of CCAM CPAM?

In about 10 percent of cases, CPAM can cause serious problems for the baby and sometimes, for the mother as well. The most serious problems occur when babies develop hydrops, a prenatal form of heart failure characterized by fluid build-up in the skin, chest or abdomen.

Is CCAM cancerous?

Congenital cystic adenomatoid malformation (CCAM) is a non-cancerous mass usually found on just one side of the lung when the tissue in the lung develops abnormally. These masses can contain fluid-filled cysts.

What is lung malformation?

A lung malformation is a mass of disorganized lung tissue that forms as the lungs of the fetus develop in the womb. The mass, or lesion, usually involves only one of the lobes of the lung. There is no known cause.

Can CCAM go away?

The CCAM may also shrink and even disappear during the third trimester of pregnancy. However, in a small number of cases, the mass may grow to be life-threatening to the fetus.

Can CPAM go away?

If the CPAM grows, which will occur in a small number of cases, it can cause increasing problems for you and/or the baby, including the development of hydrops. Most lesions will either stay the same size or actually decrease in size or disappear as the pregnancy progresses.

Can a baby survive with CCAM?

About 10 percent of all fetuses with CCAM develop hydrops. Untreated, a fetus with hydrops and CCAM usually will not survive. The mass can be so large that it limits lung development and causes pulmonary hypoplasia, or small lungs.

Is CPAM hereditary?

It happens when an abnormal mass forms in one of your baby’s lungs during pregnancy. The mass (often called a cyst or lesion) can make it harder for that lung to develop and work properly. Doctors aren’t sure what causes some fetuses to develop CPAM. The condition is not hereditary (passed down in families).

Can someone have 3 lungs?

In normal development, babies will have three lobes of the lung of the right and 2 lobes on the left. Most CLM usually arise from a single lobe but, rarely, they can affect multiple lobes. If a single lobe is involved, the most common location is in the lower lobes.

How common is CCAM?

The reported incidence of CCAM ranges from 1 in 11,000 to 1 in 35,000 live births, with a higher incidence in the midtrimester due to spontaneous resolution. BPS is even more rare, with no published population incidence.

How is CCAM treated?

Most babies with CCAM are treated with surgery soon after birth or several months later, depending on the severity of the CCAM. A small group of severe cases may be treated before birth with fetal intervention.

How is congenital cystic adenomatoid malformation of the lung studied?

The purpose of this study was to correlate CT findings of congenital cystic adenomatoid malformation (CCAM) of the lung with pathologic findings. CT scans of CCAM from 21 consecutive patients were analyzed retrospectively by two chest radiologists who achieved consensus.

What is the CT pathologic correlation for cystic adenomatoid?
