DistalCauda equinasyndrome: A case report of lumbosacral disc pathology and review of literature

Abstract

Background: Cauda equina syndrome (CES) is an uncommon entity that presents acutely with all or some of the following symptoms; urinary incontinence from retention, fecal incontinence from loss of sphincter tone, saddle area hypoesthesia or anesthesia, and acute or progressive weakness in one or both lower extremities. The protean symptomatology is often mixed and is vulnerable to confounding comorbidities making the accurate and timely diagnosis of this syndrome uniquely challenging. Here, we present the case of a man who developed isolated sacral nerve dysfunction from CES in the midst of a diabetic crisis. Case Description: A 53-year-old male with a long history of uncontrolled Type 2 diabetes presented with acute-onset urinary and fecal incontinence, scrotal anesthesia, and a 3-day history of lower back pain with intermittent bilateral leg pain. This patient displayed no objective changes in leg strength, sensation, or reflexes. In addition, the patient tested positive for cocaine and had a blood glucose level of 800 mg/dL which confounded his clinical picture. The patient underwent bilateral laminectomies from L4–S1 with the removal of a large sequestered disc fragment from the S1–S2 disc space within 8 h of presentation with reasonable recovery. Conclusion: Highly variable presentations often confound the accurate and timely diagnosis of CES with severe implications on quality of life. Despite the limited functional recovery seen after surgical decompression, urgent or emergent intervention is paramount for treatment. Our patient’s presenting symptomatology and comorbidities highlight the need for practitioners to maintain a high index of suspicion in anyone with incontinence and back pain, regardless of distractors and even in the absence of other anticipated motor or sensory findings.

Cauda Equina Syndrome Clinical Guidelines Review

“…Hyperglycemic patients often suffer from polyuria and, in some cases, reduced control of bladder function. Superimposed with back pain can create a difficult situation to specify and/ or suspect CES 35 .…”
