The term congenital lobar emphysema was used by Robertson and James (1951) to denote infantile emphysema when pulmonary infection or intrabronchial foreign bodies are absent. Although in most instances only one lobe is affected, a few patients have emphysema of more than one lobe or subsequently develop emphysema of a second lobe (Kernan, 1944; Ehrenhaft and Taber, 1953; Sloan, 1953; Potts, Hol...

Accurate diagnosis and quantification of pulmonary emphysema during life is important to understand the natural history of the disease, to assess the extent of the disease, and to evaluate and follow-up therapeutic interventions. Since pulmonary emphysema is defined through pathological criteria, new methods of diagnosis and quantification should be validated by comparisons against histological...

Pneumomediastinum is defined as the presence of air or other gas in mediastinum and also known mediastinal emphysema [1]. can be categorized spontaneous (SPM) traumatic. Traumatic pneumomediastinum caused by blunt penetrating trauma to chest, iatrogenic injury, such that produced thoracic surgery. Mechanical ventilation a common cause barotrauma pneumomediastinum. mechanical often considered ty...

background: congenital lobar emphysema, also called infantile lobar emphysema, is a respiratory disease that occurs in infants when air enters the lungs and cannot leave easily. it results from cartilage deficiency and bronchomalacia causing distal air trapping and respiratory distress. in this study, we present a case of endobronchial polyp mimicking congenital lobar emphysema. case presentati...
