As the fluid clears by absorption, the affected lung progresses from alveolar opacification to interstitial reticulation to hyperlucency. [roentgenrayreader.blogspot.com]

Congenital Malformation of the Ribs

The absence of the right breast was interpreted as being the cause of the hyperlucent lung. [mdmag.com]

The diagnosis is usually based on the physical examination (asymmetric chest) or on chest x-ray (unilateral hyperlucent lung). 1 This is not the case in our patient. [mdedge.com]

Foreign Body in the Bronchus

The finding may be subtle or absent on inspiration views; however, expiration view will demonstrate the air trapping as a unilateral hyperlucent lung that does not deflate [laryngologyandvoice.org]

Each radiograph was scrutinized for evidence of aspirated foreign body, collapse consolidation, mediastinal shift, evidence of air trapping in way of hyperlucency of the lung [jpma.org.pk]
