Spinal Intradural Juxtamedullary Cysts in the Adult: Surgical Management and Outcome

摘要: Objective Intradural nonneoplastic cysts compressing the spinal cord are rare lesions. We retrospectively analyzed a series of patients harboring this entity with regard to clinical and radiological features, surgical management, follow-up results. Methods In retrospective study, we reviewed medical charts, investigations, data 11 women 10 men (mean age, 43.6 yr) intradural juxtamedullary cysts, which were consecutively treated microsurgically at our institutions between January 1995 2003. All lesions approached via laminectomy, hemilaminectomy, or laminoplasty corresponding vertebral levels histopathologically verified. The routinely scheduled for 2 6 months after surgery. Baseline postoperative magnetic resonance imaging (MRI) was ordered Thereafter, performed 1-year intervals, neurological examination MRI. Results According presenting symptomatology, two main patient groups could be differentiated: one group myelopathic syndrome (10 patients) another predominant radicular pain (8 patients). Histopathological revealed 16 arachnoid 4 neuroepithelial 1 cervical nerve root cyst. Most (12 cases) located on dorsal aspect thoracic cord. mean craniocaudal extension these 3.7 levels, complete resection performed. four patients, cyst situated ventral involved up 17 levels. These had history major trauma, generously fenestrated its greatest circumference as depicted preoperative MRI scans. ventrolateral cord, their maximum sagittal Symptoms in all but demonstrated improvement; particular, radiating disappeared immediately There no recurrence period 3.2 years. Conclusion should considered differential diagnosis causing myelopathy and/or syndrome. Microsurgical generous fenestration large extensions effectively ameliorated patients' symptomatology. A description first documented case surgically is provided.
