Incidental Detection of Congenital Cystic Adenomatoid Malformation After Thoracoscopic Repair of Diaphragmatic Hernia

Congenital pulmonary airway malformation (CPAM) is a rare benign lung lesion, and CPAM combined with congenital diaphragmatic hernia (CDH) is extremely rare.The patient being described was a neonatal boy with a left-sided CDH diagnosed after birth.Thoracoscopic repair was performed on the first postnatal day.On chest X-ray, a suspicious lesion in terms of recurrence was observed after the postoperative follow-up period.Type 2 CPAM was diagnosed based on computed tomography.The child is doing well on postoperative period and the lesion stays stable without any intervention.Congenital lung lesions with CDH are difficult to diagnose before the CDH repair.Although very rare, congenital lung lesions concurrent with CDH should be considered when managing these patients.
