Point-of-Care Ultrasound of a Shoulder Effusion in a Child With Septic Arthritis A Case Report

Point-of-care musculoskeletal ultrasound can facilitate diagnosis of joint effusions and help guide management of suspected septic joints. This case report describes a previously healthy pediatric patient with acute onset shoulder pain and fever who was found to have leukocytosis and bacteremia. Point-of-care ultrasound (POCUS) demonstrated a unilateral shoulder joint effusion. After POCUS was performed, purulent fluid was aspirated from the joint, and she was diagnosed with a septic shoulder. We review the ultrasound technique, sonographic findings, and literature regarding POCUS for shoulder effusions.
