This article reviews the imaging and relevant clinical details of infection of the extradural spine. Spine infections are increasing in incidence and in frequency of diagnosis. They are clinically important despite their relative rarity, because they may be life-threatening, and because early diagnosis leads to improved outcomes. The focus is on pyogenic spondylodiscitis. The also typically pyogenic conditions of epidural and subdural abscess, facet joint infection, and pyomyositis are discussed. Nonpyogenic, granulomatous infections are also addressed. Magnetic resonance imaging is emphasized. The radiologist's role in performing minimally invasive sampling procedures is highlighted.
本文综述了硬脊膜外脊柱感染的影像学表现及相关临床细节。脊柱感染的发病率和诊断频率正在上升。尽管它们相对罕见，但在临床上很重要，因为它们可能危及生命，而且早期诊断可改善预后。重点是化脓性椎间盘炎。还讨论了硬膜外和硬膜下脓肿、小关节感染和脓性肌炎等典型的化脓性疾病。也涉及非化脓性肉芽肿性感染。强调了磁共振成像。突出了放射科医生在进行微创采样程序中的作用。
