Pneumomediastinum: is this really a benign entity? When it can be considered as spontaneous? Our experience in 47 adult patients

Abstract

(1) It is known that occasional consumption of cocaine causes diffuse alveolar damage, haemorrhage, etc. The cause-effect relationship consumption-appearance in a few hours of spontaneous pneumomediastinum leads us to appreciate this form of consumption as a causal factor rather than a predisposing/precipitating factor as it appears in the literature on the topic. (2) Spontaneous pneumomediastinum is considered a benign disorder but, as shown by our series, a bad outcome may represent an immediate life-threatening condition, forcing an invasive manoeuvre. We always recommend performing a chest CT scan on admission to predict the evolution.
