title: Gonococcal abscess of the obturator internal muscle: use of new diagnostic tools may eliminate the need for surgical intervention.
abstract: Obturator internal muscle (OIM) abscess or pyomyositis, a poorly recognized intrapelvic infection, is characterized by limping, pain in the hip with limited movement, and the sciatic type of radiating leg pain. With the use of advanced diagnostic tools such as computed tomography (CT), magnetic resonance imaging, and radionuclide scans, several cases of OIM abscess have been diagnosed; these cases have recently been reported in the English-language literature. Staphylococcus aureus is the predominant organism isolated from OIM abscesses. Gonococcal abscess involving the OIM has not been reported. We describe a case of gonococcal OIM abscess in an adolescent female whose condition was successfully diagnosed and managed with the use of CT-guided needle aspiration and antibiotic therapy. We review the English-language literature regarding the use of newly developed tools in the diagnosis of OIM abscess.
