We report three patients with calcium pyrophosphate dihydrate crystal deposition disease within the ligamenta flava of the cervical spine who presented with progressive myelopathy. Plain radiography showed oval calcified nodules at the level of C4-C5 and C5-C6. On computed myelography, oval calcified nodules were seen in the ligamenta flava of the posterior cervical spinal canal compressing the dural sac. Magnetic resonance revealed oval corresponding hypointense foci both on T1-and T2-weighted images. In two cases, the cervical cord showed hyperintensity at the compression site on T2-weighted images.
我们报告了3例颈椎黄韧带内存在二水焦磷酸钙晶体沉积病并表现为进行性脊髓病的患者。X线平片显示C4-C5和C5-C6水平有椭圆形钙化结节。脊髓造影计算机体层摄影显示，颈后椎管黄韧带内有椭圆形钙化结节压迫硬脊膜囊。磁共振成像显示，在T1加权像和T2加权像上均有椭圆形相应低信号灶。2例患者的颈髓在T2加权像上的受压部位呈高信号。
