MRI of paraganglioma of the filum terminale
- Cabinet of Rheumatology, Limoges (France)
Paragangliomas are benign tumors arising from paraganglionic cells of the sympathetic nervous system. They are of neuroectodermal derivation, with the majority occurring in the adrenal medulla. Extraadrenal locations are usually nonfunctioning and mostly observed (90%) in the head and neck region (carotid body or glomus jugulare tumors). Rare reported locations include the mediastinum, retroperitoneum, lungs, duodenum, and bladder. Within the CNS, paragangliomas have been observed in the pineal region, petrous ridge, sella turcica, and spinal canal. Paraganglioma of the cauda equina was first reported, but not recognized as such, in 1970. We know of 10 reports that describe MRI appearance. We present a new case and review the imaging findings of a paraganglioma of the filum terminale. 14 refs., 3 figs.
