Congenital pulmonary airway malformation (CPAM), also known as congenital pulmonary cystic adenomatous malformation (CCAM), is a rare developmental abnormality of the lower respiratory tract. Infants with this malformation may present with respiratory distress in the neonatal period or may remain asymptomatic until late in life. Many cases are detected early by routine prenatal ultrasound. Surgical resection is the definitive treatment.
