Background: Cauda equina syndrome (CES) is a consequence of a variety of etiologies. CES is most commonly due to compression of the thecal sac and nerve roots by a massive disc herniation. However, it rarely presents secondary to aortic occlusion. Aortoiliac occlusive disorder is usually associated with chronic claudication, erectile dysfunction, and diminished lower limb pulses. Acute aortic occlusion, however, is associated with serious complications such as spinal cord infarction and ischemia. It is also associated with a high risk of morbidity and mortality. Moreover, it poses a diagnostic challenge and may be overlooked. This report emphasizes the importance of considering vascular etiology as a differential diagnosis for CES., Case Description: This case report describes a unique case of aortic occlusion mimicking CES in a 56-year-old female patient., Conclusion: For patients presenting with cauda equina symptomatology, it is critical to consider vascular etiology, especially for those with cardiovascular risk factors. Spine surgeons and emergency physicians should maintain a high index of suspicion for vascular etiologies and consider appropriate imaging studies to promote early diagnosis and intervention to prevent subsequent neurological and life-threatening consequences., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Surgical Neurology International.)

Background: Spinal infections are associated with a wide variety of clinical conditions, including osteomyelitis, spondylitis, diskitis, septic facet joints, and abscesses. Based on its anatomical relationship with the dura mater, the abscess can be epidural (extradural) or subdural (intrathecal). Subdural intramedullary abscesses of the lumbar spinal canal are more common than subdural extramedullary abscesses. Here, we present a rare case of a patient with a mixed pyogenic and tuberculous epidural abscess in the lumbar spine, which perforated the dura and extended to the subdural space., Case Description: A 29-year-old male presented with progressively worsening back pain and lower-limb weakness over a period of 3 months, with an associated inability to walk, intermittent radicular pain primarily on the left side, intermittent incontinence, and a history of low-grade fever and night sweats. The patient had a history of intravenous (IV) drug abuse and reported practicing unprotected sexual intercourse. Furthermore, the patient had recently came into contact with a person diagnosed with tuberculosis (TB). The patient was administered empirical broad-spectrum antibiotics and underwent emergent L4-L5 laminectomy and spinal abscess decompression. IV antibiotics were selected based on culture results, and anti-TB medications were started. Postoperatively, the patient demonstrated a remarkable lower-limb power improvement and radicular pain alleviation., Conclusion: Spinal epidural abscess perforation of the dura and extension into the subdural space is extremely rare. Distinguishing between epidural and subdural abscesses radiologically is challenging. Multiple risk factors, such as unprotected sexual contact and IV drug misuse, may be associated with the development of polymicrobial abscesses in the lumbar spine. Careful anticipation, identification, and isolation of the causative micro-organisms can ensure effective antibacterial treatment. Early diagnosis, expeditious surgical decompression, and antibiotic treatment are associated with promising outcomes., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Surgical Neurology International.)
