title: Pulmonary barotrauma as the cause of pneumoretropharynx in pulmonary lymphangioleiomyomatosis.
abstract: A 55-year-old white woman with pulmonary lymphangioleiomyomatosis (LAM) presented to the emergency department with odynophagia and subplatysmal emphysema after a paroxysm of coughing. Lateral neck films showed subcutaneous emphysema and a retropharyngeal air stripe. Chest radiographs showed neither pneumothorax nor pneumomediastinum. Patients with LAM frequently develop pulmonary barotrauma and pneumothoracies. This patient, however, had undergone prior bilateral talc pleuradesis as treatment for recurrent pneumothoracies and, thus, could not manifest this complication of barotrauma. This case illustrates the uncommon occurrence of superior dissection of air after pulmonary barotrauma.
