Adult-onset congenital cystic adenomatoid malformation in combination with intralobar bronchopulmonary sequestration: A case report

Congenital cystic adenomatoid malformation (CCAM) and bronchopulmonary sequestration are congenital lung lesions. They are classified as separate entities. Each of them has distinct embryology, pathology, and natural history. However there are some commonalities between them. CCAM may have a pulmonary artery supply, or be supplied like a sequestration from the aorta, and histological features of both lesions may coexist [1]. CCAM is usually diagnosed before the age of 2. It is rarely encountered in adult [2]. We present an adult case of congenital cystic adenomatoid malformation in combination with intralobar bronchopulmonary sequestration.
