a rare case of mild spontaneous pneumomediastinum associated with lower respiratory tract disease with spontaneous regression
According to Hammann's pathogenetic hypothesis, later confirmed by Macklin, the rupture of the "marginal alveoli" at the basis of the pathophysiological mechanism underlying spontaneous pneumomediastinum, would be due, among the various hypotheses, to a sudden increase in intra-alveolar pressure which can be generated by an asthmatic exacerbation.This case highlights how spontaneous pneumomediastinum can be successfully managed conservatively and how the incidence of asthmatic exacerbations secondary to lower respiratory tract infections caused by atypical bacteria is common in young sexual
