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. CCAM is also frequently referred to as a congenital pulmonary airway malformation (CPAM).

Congenital pulmonary airway malformation (CPAM), formerly known as congenital cystic adenomatoid malformation (CCAM), is a congenital disorder of the lung similar to bronchopulmonary sequestration. In CPAM, usually an entire lobe of lung is replaced by a non-working cystic piece of abnormal lung tissue.

2024年8月22日 · CPAMs were previously termed congenital cystic adenomatoid malformations (CCAM). Epidemiology. They account for ~25% of congenital lung lesions.

Congenital pulmonary airway malformation (CPAM), previously known as congenital cystic adenomatoid malformation (CCAM), is a rare developmental anomaly of the lower respiratory tract . Affected patients may present with respiratory distress in the newborn period or may remain asymptomatic until later in life.

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:

A congenital cystic adenomatoid malformation (CCAM) is an abnormality of one or more lobes in which the lobe forms as a fluid-filled sac, called a cyst, which does not function as normal lung tissue. CCAMs develop with equal frequency on either side of …

What is a Congenital Cystic Adenomatoid Malformation (CCAM)? A CCAM is a benign mass of abnormal lung tissue that replaces part of one lobe of a fetal lung. CCAMs can occur in either lung and are classified into three different types based on the size of the cyst or cysts.
