Abstract

Congenital cystic adenomatoid malformation (CCAM) of lungs is a rare congenital lesion that is associated with abnormal proliferation of terminal bronchi and has an incidence of 1/4000 to 1/35000. Most of the cases (90%) are seen in the first two years of life and it is rarely seen in adolescents and the older age groups. Respiratory distress related to pulmonary compression and lung hypoplasia occur during the neonatal period, whereas recurrent and persistant pneumonia may occur at the older ages. The lesion is classified into five types by Stocker et al. Herein, we present a fourteen-year-old case who had no symptoms previously and diagnosed as type 2 cystic adenomatoid malformation with video-assisted thoracic surgery (VATS) due to persistent and treatment-resistant pneumonia.

Key words: Adolescence, congenital cystic adenomatoid malformation, pneumonia
