ABSTRACT

Congenital cystic adenomatoid malformation (CCAM) is a rare pulmonary disease. It is thought to represent the abnormal proliferation of immature alveoli and other mesenchymal components secondary to abrupt halting of terminal alveolus formation after 16 weeks of gestation. Radiographic parameters such as size, number, and content are variable. On grayscale ultrasound, anechoic, thin-walled cysts are usually noted in pleural or cardiodiaphragmatic locations. To our knowledge, there has been no report of a CCAM showing normal pulmonary vascularities. We report a case of CCAM with normal pulmonary vascularities found within the hypodense lesions on dynamic chest CT.
