The chest X-ray at birth was apparently normal [Figure 1a]. There was herniation of the left lung to the right side, causing compression of the right lung along with shifting of mediastinum [Figure 1b]. The post-operative X-ray showed a decrease in left-sided hyperinflation [Figure 1c].
(a) CT chest image showing large posterior mediastinal cyst causing attenuation of left main bronchus (black arrow) with close proximity to right bronchus (yellow arrow) and esophagus (blue arrow); (b) Cyst lined by respiratory type of epithelium consisted of ciliated pseudostratified columnar cells.(H and E, x200). CT: Computed tomography

Equal hyperinflation of the left upper and lower lobe of lung were noted [Figure 2a]. The biopsy revealed a cyst wall lined by cuboidal to psedostratified ciliated columnar lining epithelium, underlying subepithelium showing mucous glands and foci of mature cartilaginous tissue along with bronchial mucosa, suggestive of a bronchogenic cyst [Figure 2b].
