Herniation of the spinal cord

Abstract: Herniation of the spinal cord, or displacement of the cord outside the dura, is so rare that only 13 cases have been reported in the literature. The authors report a new case of spontaneous herniation of the spinal cord in a 38-year-old man who presented with lower left limb paresis and Brown-Séquard syndrome, with a T-8 sensory level. Displacement of the spinal cord was noted on computerized tomography following myelography and on magnetic resonance imaging. The herniated cord was confirmed at operation and r… Show more

“…At the time of diagnosis, 42 of the 60 patients presented with Brown-S áequard syndrome at the thoracic level, whereas nine patients had spastic paraparesis, seven presented with unilateral sensory deficit, and one each had hemiplegia and tetraplegia. These neurological deficits appear to be ascribable to damage of the unilateral and/or bilateral funiculi including the corticospinal and/or spinothalamic tracts at the site of the spinal cord herniation, 2,7) and depend on the location of the dural defect. 7) The interval between symptom manifestation and diagnosis was 6 months to 20 years.…”

“…Spinal cord herniation can be classified as spontaneous, posttraumatic, and iatrogenic [6]. Idiopathic spinal cord herniation occurs exclusively in the thoracic spine, with a female/male ratio of approximately 2:1 and it usually affects middle-age patients [2,9,10,13,15]. But posttraumatic and iatrogenic spinal cord herniation remain a rare conditions with only a small number of reports in the literature [5,7,8,12,17,18].…”

“…The outcome appears to be favorable in most 3 Spinal cord herniation into a pseudomeningocele in a intraoperative view. The small arrow shows the spinal cord herniation and the large arrow shows pseudomeningocele due to nerve root avulsion surgically treated patients, however, persistent sensory symptoms are observed in some cases [9,10,14,15].…”
