Aggressive angioblastic meningioma with multiple sites in the neural axis.

This case report illustrates a patient who was found to have multiple sites of angioblastic meningiomas in the spinal and intracranial subarachnoid space 15 to 18 years after resection of an angioblastic meningioma from the upper cervical canal. The presence of the multiple sites of tumor could represent either multicentric origin or subarachnoid seeding.
