title: Point-of-care ultrasound differentiates pyomyositis from cellulitis.
abstract: 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.
