The authors experience a rare case of the cervical radiculomyelopathy due to calcification of ligamentum flavum at the level of C4-6 and report it with review of the literature. A 60-year-old woman was admitted, complaining progressive quariparesis, gait disturbance and neck pain. She had been treated with diabetes mellitus and hypertension for several years. On radiologic study, calcification of ligamentum flavum[CLF] at the C4-6 level was demonstrated on cervical spine CT and MR scan. Decompressive laminectomy of the C 4-6 and removal of CLF were performed. During operation, thecal sac was severely compressed by hypertrophic ligamentum flavum and there were tight adhesion between calcified ligamentum flavum and dura. After the operation, her motor function and neck pain improved and she could walk with an assistant.

Ossification of ligamentum flavum(OLF) is a type of ectopic bone formation developed within the spinal ligament. Thoracic myelopathy is common symptom of OLF but radiculopathy is uncommon. We present 3 operated cases of OLF. Two showed myelopathy and one radiculomyelopathy. Main symptoms were motor weakness, sensory disturbance, incoordination of both legs, and back pain. One patient complained of left girdle pain in T4 dermatome. Deep tendon reflex(DTR) was increased in all cases. The diagnosis was made from myelogram, CT and MRI. Sufficient posterior decompressive laminectomy and medial facetectomy were performed. Postoperative diagnosis was comfirmed by histopathological examination. One patient could return to work 3 months after operation and two patients showed satisfactory improvement 2-3 months after operation. Early diagnosis and appropriate surgical treatment were prerequisite of good outcome.

Ossification of the ligamentum flavum(OLF) is not infrequent in the cervical and lumbar regions but is very rare in the thoracic spine. We reported a 62-year-old women with left thoracic intercostal neuralgia due to an OLF. Physical and neurological examination were normal. MRI showed an OLF with compression of the thecal sac in the posterolateral aspect of the T9-T10 level. Laminectomy and removal of the ligament resulted in marked clinical improvement. OLF is known to cause thoracic radiculomyelopathy, but presentation with intercostal neuralgia only is very rare.

We report a case of 29-year-old man diagnosed as a primary eosinophilic granuloma (EG) lesion of the seventh cervical vertebra. He had paresthesia on both arms, and grasping weakness for 10 days. Cervical magnetic resonance image (MRI) showed an enhancing mass with ventral epidural bulging and cord compression on the seventh cervical vertebra. Additionally, we performed spine series MRI, bone scan and positive emission tomography for confirmation of other bone lesions. These studies showed no other pathological lesions. He underwent anterior cervical corpectomy of the seventh cervical vertebra and plate fixation with iliac bone graft. After surgical management, neurological symptoms were much improved. Histopathologic evaluation confirmed the diagnosis of EG. There was no evidence of tumor recurrence at 12 months postoperative cervical MRI follow-up. We reported symptomatic primary EG of cervical spine successfully treated with surgical resection.
