脊柱结核的CT、MRI影像学特征（附34例分析）

目的探讨脊柱结核的CT、MRI影像学特征。方法回顾性分析经临床或病理证实的34例脊柱结核病人资料，CT20例，MRI24例，其中10例病人进行了MRI、CT两项影像学检查，结果相互比较。结果脊柱结核CT表现为骨质破坏、椎旁脓肿形成、椎管受累等；MRI表现为骨质破坏、椎间盘破坏、椎旁脓肿形成、椎管受累、韧带下播散等。结论脊柱结核病变具有多样性，CT和MRI影像学各有特征，CT在显示死骨、钙化等方面具有优势，而MRI在显示韧带下播散，硬膜及脊髓侵犯等方面具有优势，两者综合分析有助于脊柱结核的诊断和鉴别诊断。

CT and MRI characteristics of vertebral tuberculosis (34 cases)

Objective To explore CT and MRI characteristics of vertebral tuberculosis. Methods 34 patients with vertebral tuberculosis proved by clinic or pathology were analyzed retrospectively. Of these patients, 20 were performed with CT examination and 24 with MRI, 10 with both CT and MRI. The results were compared mutually. Results The CT features of vertebral tuberculosis were bone destruction, paraspinal abscess, spinal canal involvement. The MRI features of vertebral tuberculosis were bone destruction, intervertebral disc destruction, paraspinal abscess, spinal canal involvement, sub-ligamental spread. Conclusion Vertebral tuberculosis showed multiple characteristics on CT and MRI. CT is useful in showing sequester and calcification, and MRI is useful in showing sub-ligamental spread, epidural and spinal cord involvement. Combining CT with and MRI is helpful for the diagnosis and differential diagnosis of vertebral tuberculosis.
