Calcified Myonecrosis

Abstract

Calcified myonecrosis is a rare and late sequela of compartment syndrome. It becomes symptomatic years after the initial trauma. A 64-year-old man with calcified myonecrosis, 42 years after a shot-gun wound to the right cruris is described. He was initially treated conservatively, and although the patient vaguely recalled symptoms of a compartment syndrome, no surgery was performed. Fourty-two years later he presented with a leg soft tissue mass in the anterior compartment. A peripherally calcified, cystic soft tissue mass, continuous with the anterior tibial muscle belly was totally excised and resulted in complete resolution of symptoms. The diagnosis should be kept in mind in patients with history of major trauma and a soft tissue mass in the same compartment. Marginal excision is the treatment of choice and should be carried out when technically possible.
