1273 - Uncommon Presentation of Cauda Equina Syndrome Following Epidural Anesthesia

A 26-year-old postpartum female presented with lower extremity weakness and numbness one day after epidural analgesia. Despite no pre-existing risk factors, Cauda Equina Syndrome (CES) was suspected based on clinical symptoms, although ultimately the imaging results were inconclusive. CES is a clinical diagnosis stemming from sacral nerve root dysfunction, with either bladder and/or bowel dysfunction, saddle anesthesia, and/or sexual dysfunction. The etiologies of CES include epidural hematomas, infection, trauma, and post-spinal anesthesia. Prompt recognition and treatment are essential to prevent neurological damage in CES cases.








Case Description:

The patient is a 26-year-old female without medical history who presented with numbness and weakness in the lower extremities one day after receiving an epidural injection for pain control. The physical exam showed patchy motor weakness and paresthesias between L2-S1. The patient underwent MRI imaging of her lumbar spine which showed "diffuse thickening and contrast enhancement of the leptomeninges overlying the lower thoracic spinal cord and conus medullaris and cauda equina nerve roots in the lumbosacral spine." Based on the patient's presenting symptoms, the differential included CES, arachnoiditis, and conus medullaris syndrome. The treatment plan consisted of symptomatic support and rehabilitation. 

 

Discussions: The potential for CES to arise as a complication of epidural analgesia, though rare, underscores the critical need for comprehensive considerations and protocols in its administration, including careful selection of anesthetic agents and techniques to mitigate the risk of serious side effects. This case report exemplifies why such protocols and selection methods need to be meticulously employed.

Conclusions: This case highlights the rare but serious risk of CES following epidural analgesia, emphasizing the need for heightened awareness and stringent protocols to minimize such risks. It also raises questions about the mechanisms contributing to CES in patients without common risk factors, suggesting a need for further research to understand these rare occurrences and refine preventive strategies.
