2024年8月22日 · CPAMs are considered part of the spectrum of bronchopulmonary foregut malformations. CPAMs were previously termed congenital cystic adenomatoid malformations (CCAM). They account for ~25% of congenital lung lesions. The estimated incidence is approximately 1:1500-4000 live births and there is a male predominance.

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).

The Fetal Medicine Foundation is a Registered Charity that aims to improve the health of pregnant women and their babies through research and training in fetal medicine.

The evolution of better antenatal imaging has been crucial in changing thinking about appropriate management of congenital cystic adenomatoid malformation (CCAM). The antenatal diagnosis of this pathology has become more frequent with increasing sonographer training and higher resolution ultrasound imaging platforms.

2019年2月16日 · CPAMs are unilateral 98% of the time and appear as echogenic areas of the lung, with or without identified cysts. The CPAM volume ratio (CVR) can be used to subdivide these malformations into high- and low-risk categories for development of fetal hydrops. Fluid-filled dilated airways should raise suspicion for bronchial or laryngeal atresia.

Congenital cystic adenomatoid malformation (CCAM) recently being referred as congenital pulmonary airway malformation (CPAM), is a rare congenital pulmonary anomaly with reported incidence of 1 in 25,000–35,000 live births. 1 On antenatal ultrasonography (USG), characteristic appearance of lesion not only helps in diagnosing it but also ...

2015年6月1日 · Congenital cystic adenomatoid malformation (CCAM), or congenital pulmonary airway malformation, is a rare but potentially life-threatening abnormal development of the lung during embryogenesis. It presents as a single or multiple cystic area, in one or both lungs. 1 - 4

2019年9月22日 · Congenital cystic adenomatoid malformation (CCAM) is a rare developmental abnormality of the lungs. It is characterized as a benign hamartoma or dysplastic lung tumor due to overgrowth of terminal bronchioles. The tumor can grow to be quite large, compressing adjacent lung tissue and impairing growth of normal pulmonary tissue.

2019年7月7日 · CCAM is the most common fetal hyperechogenic lung lesion and accounts for 50% to 75% of detected fetal lung abnormalities. These lesions may display dramatic changes during pregnancy, with spontaneous regression and total resolution in more than half of cases.

2023年9月12日 · Congenital pulmonary airway malformation is the most common congenital lung lesion of the lower respiratory tract. It was formerly known as congenital cystic adenomatoid malformation (CCAM). 1 The name was changed to better conform to the histologic variety. CPAM occurs with a reported incidence of 1 in 10,000-35,000 births.
