===== Case reports =====

Herman et al. reported a case of [[Cauda equina paraganglioma]] and reviewed the MRI features in 11 previously published cases with MRI description. On T1-weighted images, paraganglioma is isointense relative to spinal cord and shows moderate to intense enhancement after Gd-DTPA application, usually with heterogeneous texture. On T2-weighted images, different findings were found. MRI features do not allow to distinguish paraganglioma of the cauda equina from majority of other tumors in this region
