Acute Paraplegia From Hemorrhagic Paraganglioma Of Filum Terminale: Case Report And Review Of Literature

Paraganglioma (PGL) of the filum terminale is a rare tumor of extra-adrenal paraganglia. The reported cases of filum terminale and cauda equina PGLs often present with low-back pain and sciatica. While sensory or motor deficits and paraplegia may occur, the incidence is relatively low. We present a case of a 51-year old male with hemorrhagic paraganglioma of the filum terminale. He presented with acute paraplegia and was treated via emergent laminectomy, evacuation of hematoma, and resection of tumor. The patient had a significant but incomplete neurological recovery. The clinical, radiologic, and histopathological characteristics of the condition are described.
