Giant Congenital Lobar Emphysema: A Rare Cause of Persistent Respiratory Distress in Neonatal Intensive Care

Abstract

Congenital lobar emphysema (CLE) is a rare congenital anomaly of the lung causing excessive aeration of one or more lobes of a histologically normal lung. It manifests in the first weeks of life and rarely in the neonatal period, with respiratory distress due to compression atelectasis and often associated with mediastinal displacement. CLE poses a challenge in terms of diagnosis and positive pressure ventilation due to air trapping. We report the case of a newborn presenting with persistent respiratory distress. A thoracic CT scan was performed, confirming the diagnosis of CLE. The definitive diagnosis is provided by histology of the operative specimen, revealing emphysematous lesions. Treatment involves lobectomy after stabilization of respiratory function. Surgical abstention is possible for asymptomatic or paucisymptomatic lesions.
