Paraganglioma of the Filum Terminal: Case Report and Review of the Literature
2020
Abstract Paraganglioma of the filum terminal/cauda equina is a rare slow growing tumor which originates from the ectopic sympathetic neurons. Surgically, total excision may be difficult for this well demarcated tumor surrounded by couple of rootlets but is usually possible in nearly all cases. Actually, final diagnosis cannot be determined intraoperatively, but is possible only after an immunohistochemical staining. Herein, the authors present a middle age woman whose initial symptoms were lower back pain and radiculopathy. Her MRI was found to be compatible with a cauda equina tumor. During her excisional surgery a hard and relatively vascular tumor was fully removed. The Immunohistochemical results were compatible with paraganglioma of the filum terminale. In addition to case presentation, thorough review of the literature is also done.
