摘要
目的 探讨脊柱结核的MRI表现及早期诊断。材料与方法 对 2 2例脊柱结核行矢状位T1WI、T2 WI、P(N)I及轴位T1WI ;12例行Gd DTPA增强T1WI。观察椎体、终板、椎间盘和冷脓肿的信号变化和增强后改变。结果 (1)椎体骨炎及终板破坏呈长T1长T2 信号 ;(2 )椎旁或椎前冷脓肿呈长T1长T2 均匀无结构信号 ,且上下跨越范围较大 ;(3)早期椎间盘信号正常或只出现退变 ,晚期则被破坏 ;(4 )Gd DTPA增强扫描可清楚显示冷脓肿周围纤维肉芽组织及椎管内侵犯 ;(5 )骨内小脓肿和 /或椎旁脓肿、椎体终板破坏是MRI诊断早期脊柱结核的重要依据。结论 MRI可清楚显示脊柱结核的椎体骨炎、椎旁脓肿、终板破坏和神经损害 。
Objective To investigate the MRI features and early diagnosis of tuberculosis of spine.Materials and Methods Sagittal T 1WI, T 2WI, P(N)I and axial T 1WI were performed in 22 cases with tuburculosis of spine. GdDTPA enhanced sagittal and axial T 1WI scanning was performed in 12 cases. The signals of vertebrae, endplates, intervertebral discs and abscess at every sequence and series were observed.Results (1) Osteitis and destruction of endplate showed long T 1 and long T 2. (2) Anterior and lateral abscess had long T 1 and long T 2 presenting even and structureless signal. (3) The intervertebral discs showed normal or only degeneration at the early stage, and destroyed at later stage. (4) With GdDTPA enhancement, fibrotic granulation around abscess and destroyed area was well demonstrated. (5) Abscess in the bone and/or paraspinal abscess, destruction of endplate were the important evidence for early diagnosis.Conclusion MRI can well demonstrate osteitis, abscess, destruction of endplate and neurological deficit, providing useful information for the diagnosis of early and atypical spinal tuberculosis.
