Pyomyositis of the Iliacus Muscle in an Adolescent

Authors: David Zlotkin, MD


A ten-year-old female presented to the Emergency Room with the acute onset of left hip pain and was non-ambulatory when she was admitted to the hospital. On initial examination, she was in severe pain. She was afebrile with stable vital signs. The hip appeared normal, with no erythema or swelling, although it was very tender to palpation. She denied pain in other regions. The remainder of her physical exam and her past medical history were non-contributory. Initial laboratory findings showed a normal complete blood count with differential (CBCD), complete metabolic panel (CMP), and erythrocyte sedimentation rate (ESR). Plain films of her hip, femur and pelvis were negative, as was an ultrasound of her left hip.
