Post-traumatic subcutaneous emphysema - Is it always a sign of alarm? - Abstract

Catarina Ladeira, Aline Vaz-Silva, João Pascoal



Benign subcutaneous emphysema is a rare condition that commonly occurs secondary to trauma. We present a case of a child with a post-traumatic subcutaneous emphysema of the lower limb wrongly diagnosed as a necrotizing fasciitis. It is important to differentiate benign subcutaneous emphysema from serious soft-tissue infections such as gas gangrene and necrotizing fasciitis as the management, treatment and prognosis differ significantly.

Keywords: benign subcutaneous emphysema, necrotizing fasciitis
