Obturator Internus Pyomyositis: A Case Report

ABSTRACT

Pyomyositis is a primary bacterial infection of skeletal muscle and this is on the increase worldwide among children as well as young adults. We report herein on a case of a 29-year-old male with pyomyositis of the obturator internus. The fact that pyomyositis predominantly affects the muscles of the lower limb and it is confined to the obturator internus muscle has been poorly recognized. CT with an enhancement was an accurate imaging modality to image the obturator internus muscle and to ascertain the diagnosis for this case. The patient was managed with antibiotics and surgical intervention was not necessary. Pyomyositis of the obturator internus muscle needs to be differentiated from septic arthritis of the hip. The present study reports the clinical signs and treatments of pyomyostis and we review the relevant literature.
