The guidance for clinicians on who requires further investigation when suspecting cauda equina syndrome has become clearer in England following the publication of the national recommendations. This does not have specific advice for those patients who have had recent imaging with no compression, returning to a healthcare provider with a change in symptoms. These cases can cause difficulty for clinicians with limited access to imaging who can often be reassured by previous imaging. This study presents a retrospective review of the case notes of 45 patients presenting on two occasions to the same Emergency Department who underwent magnetic resonance imaging due to the clinical diagnosis of cauda equina syndrome. Those with compression of the cauda equina on the second visit were compared to those without a compressive cause for their symptoms. Patients presenting with an increased number of clinical symptoms associated with cauda equina syndrome on their return visit were more likely to have compression of the cauda equina on imaging. The small numbers in this study would suggest caution, however, if patients present with an increasing number of symptoms further imaging should be considered, even with previous reassuring scans.
