Abstract

Cystic adenomatoid malformatian is characterised by maturation failure of bronchial structures and multiple cysts in varying shapes in the lung tissue. The course of the disease may be asymptomatic, but in some cases the clinical manifestations may consist of respiratory distress, tachypnea, recurrent respiratory tract infections and cyanosis. Recently cystic adenomatoid malformatian can be diagnosed by prenatal ultrasonography in the early stages of the disease. Postnatally, chest roentgenogram and computerised tomography may be helpful in the diagnosis of the disease. Lobectomy, surgical resection or segmentectomy are recommended procedures in order to relieve the pressure of the cysts on the lung tissue and maintain the maturation of the lung. There are 3 types of cystic adenomatoid malformation. Our case was presented herein due to cystic structures broader than 2 cms in diameter, asymptomatic course, prenatal diagnose, and its rarity.
