Question

Quizplus · Accepted Answer

PIE (Pulmonary Interstitial Emphysema) is a term used to describe the accumulation of air in the interstitial spaces, typically in neonates. The characteristic findings on chest radiograph include a fine, bubbly appearance of the lungs caused by air-trapping in the interstitial spaces. Lung hyperinflation, which is also seen in PIE, is another prominent finding. Mediastinal shift and air below the diaphragm are not specific findings for PIE and are more commonly seen in conditions such as pneumothorax and pneumoperitoneum respectively. Therefore, choice C (3, 4) is the best choice.
