目的 探讨艾滋病患者椎旁脓肿 的CT及MRI影像学表现。方法 回顾性分析 35例艾滋病患者椎旁脓肿的CT及MRI影像 表现。结果 35例艾滋病相关椎旁脓肿， 结核性脓肿30例，非特异性化脓性脓肿5 例。23例出现脊柱骨质破坏者均为结核性 脓肿，其中4例患者可见椎体塌陷；14例 病变可见硬膜外脓肿，其中13例为结核性 脓肿。结论 艾滋病患者椎旁脓肿以结核 分枝杆菌感染多见，影像表现上结核分枝 杆菌骨质破坏分布范围更广泛，常见硬膜 外脓肿，磁共振及CT检查为首选影像检查 方法。

Objective To study the CT and MRI imaging features of paraspinal abscess in AIDS patients. Methods Retrospective review of CT and MRI imaging features of 35 patients with AIDS-related paraspinal abscess. Results In 35 cases of HIV/AIDS, 30 cases are tuberculosis, 5 cases are non-tuberculous mycobacteria, 23 cases with bone destruction is TB, Vertebral collapse in 4 patients, 14 cases of epidural abscess,among these 13 cases were tuberculosis patients. Conclusion For Most AIDS patients with vertebral abscess by Mycobacterium tuberculosis infection,CT and MRI showed that the bone destruction of Mycobacterium tuberculosis was more extensive,common epidural abscess. MRI and CT are preferred imaging methods.
