Paraganglioma of the cauda equina: MR findings. One case

Paraganglioma of the filum terminale is a rare tumor but well described in the neurosurgery and pathology literature. Few MRI reports are mentioned. Paraganglioma, often misdiagnosed with ependymoma or schwannoma on MRI images, must be kept in mind, when a highly vascular lesion with serpentine vessels is observed.
