摘　　要：目的探讨臀肌化脓性感染的MRI诊断及其临床意义。方法回顾性分析经手术或穿刺活检证实的12例臀肌化脓性感染的临床及MRI资料。结果12例罹患臀肌弥漫性肿大,病变顺肌肉长轴发展为主,累及臀肌全部或大部,基本征象为肌肉水肿、坏死及脓肿形成。8例亚急性或慢性感染出现纤维肉芽组织增生,不同病变MRI信号各具特点。5例表现为化脓性肌炎,炎性水肿较为广泛;7例形成典型肌肉脓肿,脓腔较大或以脓腔为主。5例化脓性肌炎应用抗生素治疗,7例肌肉脓肿行穿刺或切开引流术,均获治愈。结论MRI能够反映臀肌化脓性感染各个时期的病理特征及病变范围,并可正确诊断,对临床治疗具有重要指导意义。Objective To explore the MRI diagnosis of the pyogenic infection in gluteus muscles and its clinical significance. Methods The clinical and MRI data of 12 cases with the pyogenic infection in gluteus muscles proved by operation or biopsy were retrospectively analysed. Results The MRI of the 12 cases displayed that the infective gluteus muscles were swelling diffusely and the infections developed along the long axis of the muscles and most or all gluteus muscles were involved in. The basic characteristics were edema and necrosis of the muscles and abscess. The fibro-granulation tissue hyperblastosis occurred in 8 patients with subacute or chronic infection. The different affections had different features. Suppurative myositis was displayed and had been cured by antibiotics in 5 patients. Typical abscess in muscle was developed and had been cured by paracentesis or incision and drainage in 7 patients. Conclusion The pathological characters of the every stage and extent of the pyogenic infection in gluteus muscles can be displayed by MRI. MRI can be used in diagnosing the pyogenic infection in gluteus muscles accurately and has important guiding meaning for clinical treatments.
