“…The aforesaid observations may confound the role that COVID-19 plays in the development of SPM. Patient 1 represents one of the few cases in the published literature of SPM diagnosed on presentation at the emergency department, at the beginning of oxygen support therapy [ 7 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ]. These cases are of great importance because they suggest that there must be an inherent component in the COVID-19 infection that predisposes to air leaks, which can precipitate with anything that increases the alveolar pressure [24] .…”

Spontaneous pneumomediastinum (SPM) is a rare complication of coronavirus disease 2019 (COVID-19). The published literature consists mainly of case reports and small case series. There are still many questions regarding the pathogenesis, the prognostic significance and the implications on patient management. In our hospital three COVID-19 patients developed SPM: one on admission at the emergency department and the other two during hospitalization. In this study we describe their clinical course and computed tomography (CT) findings. All of them had severe disease according to the total severity score on admission CT. The management of pneumomediastinum was conservative and follow-up CT showed resolution in all patients. As the correlation between extension of parenchymal lung lesions and development of pneumomediastinum is still under investigation, we highlight the importance of reporting the severity score on chest CT in order to obtain more comparable results between different studies. Furthermore, in this tragic circumstance we also had the opportunity to familiarize ourselves with the otherwise uncommon occurrence of air along the bronchovascular sheaths (Macklin effect) and evaluate the ability of CT to detect it.
