Incidentaly Found Congenital Cystadenomatoid Malformation in a Misdiagnosed Case of Massive Pneumothorax, in a 2 Months Old Child

Congenital cystic adenomatoid malformation (CCAM) of the lung is a rare congenital pulmonary developmental malformation, found in terminal respiratory structures. It is characterized by a multicystic mass of pulmonary tissue with an abnormal proliferation of the bronchial structure. Most patient present with recurrent fever, cough and respiratory distress. It can very well misdiagnosed as massive pneumothorax and may land up in Intercostal drainage tube (ICD) insertion. We report one such case of Type 1 CCAM in a 2 month old female child in whom ICD was put thinking of massive pneumothorax.
