title: Calcium pyrophosphate dihydrate crystal deposition disease in cervical radiculomyelopathy.
abstract: One patient had cervical spinal canal stenosis with radiculomyelopathy due to deposition of calcium pyrophosphate dihydrate within the ligamentum flavum. The MRI of cervical spine showed a calcified nodule over C5-6 level ligamentum flavum with obvious cord compression. After posterior decompressive laminectomy with removal of the calcified nodule, the symptom and sign relieved remarkedly and the pathology showed calcium pyrophosphate dihydrate deposition within the ligamentum flavum. We presented this case and reviewed the literature to acknowledge so-call "pseudogout syndrome."
