We report a case of subcutaneous emphysema and pneumomediastinum secondary to pyomyositis and necrotizing fasciitis over the right arm of a woman with underlying diabetes mellitus and iatrogenic Cushing syndrome. Gas produced by the culprit pathogen extensively dissected the subcutaneous fat and fascia of the patient's right arm and distantly spread to her face, neck, back, and thoracic wall and penetrated the soft tissue cephalically bordering her sternum, resulting in pneumomediastinum. The patient improved-with antimicrobial therapy and localized debridement and fasciotomy over her right arm.

Pyomyositis (PM) is an infection of skeletal muscle, often associated with an abscess. Patients typically have predisposing risk factors or are immune compromised. The disease is often misdiagnosed, mistreated,and goes undetected until late in the patient's clinical course.We present a case of a patient without obvious predisposing risk factors who complained of right thigh pain, swelling, redness, and fevers for 4 days.Point-of-care ultrasound revealed muscle edema and subcutaneous emphysema without signs of an overlying cellulitis. Point-of-care ultrasound consequently led to an earlier diagnosis of PM and directly affected the immediate patient care in the emergency department.
