Disseminated osseous tuberculosis is a rare disease. This is a report of two cases of disseminated osseous tuberculosis imaged with MRI at 1.5-T, CT, plain radiography and bone scintigraphy. CT and plain radiography demonstrated either highly destructive or cystic lesions with sclerotic margins. Bone scintigraphy and plain radiography were quite insensitive in detecting areas of involvement compared to MRI. On MRI the abnormal areas had short T-1 relaxation values, which is an atypical appearance for bony infections, and prolonged T-2 relaxation values. The reason for the T-1 relaxation behavior is uncertain. MRI also provided delineation of epidural extent.
播散性骨结核是一种罕见疾病。本文报告两例播散性骨结核病例，均采用1.5-T磁共振成像（MRI）、计算机断层扫描（CT）、X线平片及骨闪烁显像进行检查。CT和X线平片显示为边界硬化的高度破坏性或囊性病变。与MRI相比，骨闪烁显像和X线平片在检测受累区域方面相当不敏感。在MRI上，异常区域的T1弛豫值较短，这在骨感染中是非典型表现，而T2弛豫值延长。T1弛豫表现的原因尚不确定。MRI还能显示硬膜外受累范围。
