Chest radiograph at age of 15 months

Overinflation of the left upper lobe, displacing the heart and mediastinum to the right.
The right lung is clear.
The heart is normal in size.

Case Discussion

The first chest X-ray on the day of birth was misleading, as it were, as the left upper lobe was radiopaque. In the early neonatal period, the affected lobe contains fetal fluid and tends to be homogenously radiopaque or may show diffuse reticular pattern representing distended lymphatic channels. Subsequent radiograph shows progressive overinflation of the left upper lobe, in keeping with a congenital lobar overinflation.
