A mixed lung lesion consisting of a combination of bronchogenic cyst , bronchopulmonary sequestration and congenital cystic adenomatoid malformation suggest a embryologic link for these malformation. The true incidence of congenital lung lesion is unknown. The huge fetal lung lesion have reproducible pathophysiologic effects on the fetus. we are presenting a very rare presentation of this hybrid lesion. 3 months old male child presented with history of recurrent episodes of fever and respiratory distress.Child was evaluated with CT chest with pulmonary angiogram and diagnosed as a case of CCAM with BPS. Hence we p r o c e e d e d w i t h t h o r a c o t o m y a n d l o w e r lobectomy.Histopathology report came as hybrid lesion (CCAM with BPS). Post-op period was uneventful.
