Abstract

Obturator internus muscle (OIM) abscess associated with pelvic superior ramus osteomyelitis is a rare condition, most often described in children following trauma or strenuous muscular activity. Positive blood cultures, when present, are typically due to Staphylococcus aureus. We report the case of a 12-year-old male who presented to the Emergency Department at Prince Ali Military Hospital, Al-Karak, in March 2024 with fever and right hip pain. Magnetic resonance imaging (MRI) confirmed an OIM abscess with superior ramus osteomyelitis. Culture of drained pus and soft tissue samples grew Staphylococcus aureus. The patient underwent surgical drainage and received intravenous antibiotics, which led to full recovery. This case highlights a rare presentation of OIM abscess with associated pelvic osteomyelitis. Early recognition, timely surgical drainage and debridement, combined with systemic antibiotic therapy, can lead to excellent outcomes.

小儿闭孔内脓肿及上支骨髓炎1例报告

闭孔内肌（OIM）脓肿合并盆腔上支骨髓炎是一种罕见的疾病，最常见于儿童外伤或剧烈肌肉活动后。血培养阳性，当存在时，通常是由于金黄色葡萄球菌。我们报告了一名12岁男性病例，他于2024年3月因发烧和右髋关节疼痛来到Al-Karak阿里王子军事医院急诊科。磁共振成像（MRI）证实OIM脓肿合并上支骨髓炎。排出的脓液和软组织样本培养出金黄色葡萄球菌。患者接受手术引流并静脉注射抗生素，最终完全康复。这个病例强调了一个罕见的OIM脓肿合并盆腔骨髓炎的表现。早期发现，及时手术引流和清创，结合全身抗生素治疗，可导致良好的结果。
