A Case of Unknown Cause of Subcutaneous Emphysema Presented by Generalized Edema

ABSTRACT

Subcutaneous emphysema and pneumomediastinum are commonly derived from trauma or injury of respiratory or gastrointestinal tracts, but occasionally the origin of air was not determined at evaluation. We report on a case of severe subcutaneous emphysema detected using simple X-ray films in the emergency department, which extended to almost all of the bodies, with a review of the literature.
