Fig.1: Antenatal sonography monitoring (a) in the 23rdweek, there were well-defined cystic structures in the left lung accompanied by mild polyhydramnios (b) in the 26thweek, a 20×40 cm anechoic multicystic lesion was occupying the left side of the thoracic cavity with moderate polyhydramnios.
Fig.2: (A) postnatal plain trunk X-ray with mild diffuse opacity on the left side that suggests a large cystic lesion and mediastinal shifting to the right. (B) plain trunk X-ray with oral contrast assures the absence of the diaphragmatic hernia.
Fig.3: CT scan of the chest with contrast suspects of 20×40 cm CPAM in the left lower lobe consisting of enhanced solid mass in the posterior part associated with a multicystic structure located anteriorly with compensatory hyperinflation of the left upper lobe, which causes the lung herniation to the right side.
Fig.4: Open left lower lobectomy via a left posterior thoracic approach.

ECHO = Echocardiogram. *  Multiple courses of betamethasone may be an option. (B) Postnatal management algorithms of CPAM by David et al (2016).
ECHO = Echocardiogram; PPHN = persistent pulmonary hypertension of the newborn; ECMO = extracorporeal membrane oxygenation.
