Case reports of symptomatic metastases in four patients with primary intracranial gliomas.

Four patients with primary intracranial high-grade gliomas are reported. Three of them developed spinal symptoms and signs generated by spinal metastases a few months after first diagnosis, the last patient developed an extraspinal metastasis in cervical lymph nodes. The spinal metastasis of a 30 years old patient was located intradurally at L5/S1, in the second patient at level L3, the third patient presented with multiple metastases in the cervical, thoracic and lumbar spine. Previously reported cases are reviewed, are discussed in the light of our own observations and analysed for the various therapeutic options.
