Introduction: The cauda equina is the collection of L2 – L5 nerve roots originating from the terminal portion of the spinal cord (conus medullaris). Tumours involving the cauda equina are uncommon, however are most commonly myxopapillary ependymomas (MPE). Other differentials to consider include spinal schwannoma and paraganglioma. Aim: To review the MR imaging features of common differential diagnoses of cauda equina tumour in adults – MPE, spinal schwannoma and paraganglioma. Method: In this pictorial review, multi-phase MR images will be presented to demonstrate characteristic features of cauda equina tumours. The normal terminal spinal cord anatomy will first be reviewed, followed by features characterising myxopapillary ependymoma, spinal schwannoma and paraganglioma. Results: Characteristic findings of the above tumours are discussed. In particular, patterns of enhancement, location, presence of haemorrhage and quantity of tumours can help discriminate between these tumours. Conclusion: Although MPE is the most common cauda equina tumour, the list of differential diagnoses is long. Identifying certain MR features of these neoplasms can aid in pathological diagnosis and thus, influence surgical management.
