Intradural paraganglioma of the thoracic spine.

Extraadrenal paragangliomas are usually located in the head and neck region, with 90% arising in the carotid body or glomus jugulare (1) . These tumors have also been located in a number of other areas, including, rarely , the spinal canal (1-7). Previously reported intraspinal paragangliomas have all been located in the intradural compartment in the region of the cauda equina, with the exception of three epidural thoracic lesions (1 , 2). We now report what we believe is the first case of a purely intradural thoracic region paraganglioma.
