title: Paraganglioma of the filum terminale presenting with normal pressure hydrocephalus.
abstract: We describe a patient with an intraspinal paraganglioma who presented with normal pressure hydrocephalus. A 70-year-old man presented with a 6-month history of gait disturbance and cognitive dysfunction. Computed tomography of the brain and magnetic resonance imaging of the spine revealed communicating hydrocephalus and a spinal mass at the T12-L1 level which proved to be a paraganglioma of the filum terminale. Radioisotope cisternography revealed a severe delay in cerebrospinal fluid circulation. Symptoms related to communicating hydrocephalus resolved after tumor resection.
