Spontaneous pneumomediastinum: is a chest X-ray enough? A single-center case series.

Abstract

SPM is a rare entity that should be considered in patients with pleuritic chest pain. Treatment is supportive, and if no clues for esophageal rupture are present, investigations other than chest X-ray are probably not warranted. It is safe to discharge the patient within 24 hours provided that symptomatic improvement is achieved.
