Radiologic Findings

Frontal radiograph (Fig. 34A) of a term newborn infant demonstrates perihilar streaky opacities, mild cardiomegaly, hazy vascular markings, diffuse interstitial pulmonary edema, and prominent fissures with a small, right pleural effusion. The lung volumes are slightly increased. Frontal radiograph performed the next day (Fig. 34B) on the same child demonstrates rapid resolution of the previously noted abnormalities.
