Abstract
Congenital lobar emphysema (CLE) is a rare respiratory disorder which allows air to enter the lungs but can’t escape causing over-inflation of the lobes of the lung. This condition (CLE) is commonly detected in the newborn or young infants but some cases are diagnosed in adulthood. Congenital lobar emphysema is a rare congenital malformation with a prevalence of 1 in 20,000 to 1 in 30, 000, and more prevalent in males, with a male to female ratio of about 3:1. This is a 17 day old male neonate that presented with respiratory difficulty and .had a supine chest radiograph that showed an overinflated left lung field more on the upper and middle zones with flattening of the left hemi diaphragm, marked shift of the heart and mediastinum to the right with some degree of loss of volume involving the right lung. We report the radiographic findings of this case due the rare nature of congenital lobar emphysema.
Highlights
Congenital lobar emphysema is a rare malformation of lung development characterized by over distension of a lobe following partial obstruction of the bronchus [1,2]
Congenital lobar emphysema been a rare disease may be the cause of severe respiratory distress in the infant and neonates [1,5]
Congenital lobar emphysema is usually unilateral affecting the upper left lobe in about 43%, followed by the middle right lobe in 32%, with bilateral involvement of the lobes of the lung been reported [9,11,12]
Summary
Congenital lobar emphysema is a rare malformation of lung development characterized by over distension of a lobe following partial obstruction of the bronchus [1,2]. Congenital lobar emphysema been a rare disease may be the cause of severe respiratory distress in the infant and neonates [1,5]. Congenital lobar emphysema is a reversible and possibly life threatening cause of respiratory distress in the neonatal period, as many as 25% of the patients, presentation may be delayed until the first month of life [6].
