Case Report
A 30-year-old pregnant female with an unremarkable surgical, medical, drug or family history presented in the 13th week of gestation for a routine Ultrasound (US) examination which revealed a cystic formation in the left lung of the fetus associated with mild polyhydramnios. The patient was asymptomatic and physical examination was unsignificant, By monitoring, and during the 23rd and 26th weeks of gestation, the lesion was stable and there was a slight increase in the amniotic liquid (Fig.1). In the 39th week of gestation, the woman underwent caesarean delivery and had a 3400 g weighing male who was admitted to the neonatal intensive care unit by their parents and referred to the Department of Pediatric Surgery complaining from severe respiratory distress worsening during lactation, and it was decided to stay in the incubator for 24 hours. The chest radiography indicated the deviation of the mediastinal structures toward the right-side Fig.2 (A). Chest radiography with oral contrast excluded the presence of diaphragmatic hernia Fig.2 (B). At the age of 14 days, a (computed tomography) CT scan of the chest with contrast was performed and the diagnosis of CPAM was confirmed at the expense of the lower left lobe (Fig.3). Except for the right axis deviation, echocardiography did not indicate any cardiac abnormalities. Upon completion of preoperative procedures, the 14-day-old patient underwent an open left lower lobectomy via a left posterior thoracic approach (Fig.4), and pathology studies of the resected part confirmed the diagnosis of CPAM. The infant received post-operative care with incubation for 3 days. On the third day after the operation, chest radiography demonstrated the return of mediastinum to the midline, and a compensatory hyperinflation of the residual lobes of the left lung. Finally, the infant weaned off the respiratory support and was discharged home at the age of 17 days without any complications. During follow-up, the infant’s condition was found to be satisfactory.
