ABSTRACT
Spinal cord infarction (SCI) is a rare vascular event accounting for 1% of all strokes. Neurological syndromes may vary according to the arterial territory involved. This condition may differ in onset, severity, and recovery, making it a diagnostic challenge for clinicians. Diagnosis is made on a clinical basis, and neuroimaging (magnetic resonance imaging (MRI)) provides confirmatory evidence. A 72-year-old male, with a medical history of being overweight, hyperuricemia, dyslipidemia, and cigarette smoking presented to our emergency department (ED) with sudden-onset leg weakness. He reported chest pain with radiation to the back, followed by sudden arm and leg weakness, evolving to inferior limb plegia within four hours. He also noticed a loss of sensation below the breast region. On admission, vital signs were stable. Neurological examination demonstrated paraplegia of inferior limbs with absent deep tendon reflexes. Both pinprick, vibrational, and proprioceptive sensitivities were absent below T6. A diagnostic workup revealed lactescent serum suggesting severe hypertriglyceridemia. A clinical diagnosis of spinal cord infarction was made, which was later confirmed with MRI demonstrating an acute ischemic lesion in the anterior spinal artery (ASA) with the "owl's eye" sign, from T5 with extension to the cone. Neurological examination remained unaltered. He started aspirin and insulin perfusion. Since spinal cord injury is an uncommon cause of paraplegia, physicians should be extremely cautious. Despite the results of magnetic resonance imaging, the clinical picture was not consistent, which was finally explained by perilesional edema. To our knowledge, this is a rare case combining SCI with hypertriglyceridemia. Notwithstanding the lack of evidence linking reducing triglyceride levels to neurological recovery, insulin infusion was carried out given the hazards associated with sustaining such high levels of triglycerides. We aim to emphasize some characteristic MRI findings and the wealth of possible etiologies contributing to this clinical entity.
