Paraganglioma is a neuroendocrine neoplasm composed largely of paraganglion chief cells. The most common site of paraganglioma is the adrenal medulla, carotid bodies and glomus jugular. Recently molecular characterization of CNS paragangliomas identifies cauda equina paragangliomas as a distinct tumour entity.

Magnetic resonance imaging is the exam of choice. On MRI iso or hyperintense on T1-weighted images and isointense on T2-weighted images with serpentine vessels have been highlighted as a hallmark of this tumour.
