What does CLE stand for?

Chest X-ray findings may be confused in situations such as pulmonary hypoplasia where the decreased lung volume and density may be misinterpreted as collapse, or congenital lobar emphysema which may be mistaken for a pneumothorax.

[FIGURE 1 OMITTED] [FIGURE 2 OMITTED] [FIGURE 3 OMITTED] [FIGURE 4 OMITTED] DIAGNOSIS Congenital lobar emphysema (CLE) IMAGING FINDINGS A histologic view of the lung parenchyma affected by CLE revealed the characteristically enlarged and overdistended alveoli and rupturing of the interalveolar septae due to the overdistension.

The differential diagnosis for SJMS includes congenital lobar emphysema and a host of acquired causes; acquired causes include lung abscess (post-pneumonic or postaspiration), bronchiectasis, cavitating lesions (tuberculosis and Wegener's granulomatosis), cystic states (tension bronchogenic cysts), pulmonary vascular disease, and central obstructing lesions (tumors and foreign bodies).
