Intradural extramedullary spinal cord tumors: a retrospective study at tertiary referral hospital

Abstract

Introduction: Intradural extramedullary (IDEM) spinal cord tumours account two thirds of all intraspinal tumours. The objective of this study was to determine short- and long-term outcomes of surgical patients with IDEM spinal cord tumours, and to see clinical features that could be helpful in management of patients with these lesions (operated by single senior surgeononly). Methods: A retrospective review of 201 operative IDEM spinal cord tumours cases between 1993 and 2014 was performed. Outcomes were scored at one month and at mean follow-up of 8.5 months postoperatively. In addition, patient demographics, tumour types and locations were also collected. Statistical analysis was conducted utilizing Chi-square and Student's t-tests. Results: There were 93 men and 108 women (mean age 48 yrs, range 5-87 yrs). Men presented at a younger age than women (42 vs 51 yrs, P<0.02). 165 (82.08 %) patients presented with severe radiculopathy and myelopathy. The 36 (17.91 %) had symptoms of radiculopathy. Mean duration of symptoms prior to diagnosis was 11 months. Schwannomas (113 patients) had the longest mean duration of symptoms (14.9 months), followed by meningiomas (68 patients, 8.4 months), and ependymomas (20 patients, 2 months). Hundred and eighty nine (94%) of patients demonstrated significant improvement at one-month and 186 (92%) at 6-month mean follow-up. Only 39/201 (19.4%) patients had residual focal deficits on long term follow-up. Conclusions: Surgery for IDEM should be expected to produce significant and dramatic improvement in most of patients. Demographic, tumor-specific and anatomic considerations will be clinically useful while managing IDEM.

Clinical outcome of intradural extramedullary spinal cord tumors: A single-center retrospective analytical study

“…Intradural extramedullary tumors, that are typically benign, account for two-thirds of primary spinal tumors. [ 4 ] Their location determines the clinical presentation, ease of surgical excision, and outcome. Plain radiograph can help to identify pedicle erosion, vertebral body erosion, foraminal widening, and scoliosis.…”

Unilateral laminectomy approach for total resection of intradural extramedullary spinal tumor

“…Intradural-extramedullary tumors accounted in primary spinal tumor and most of the intradural-extramedullary spinal tumors are benign with meningioma and schwannoma as the most common pathological finding for this type of tumor. 1,2 Conventionally, intradural-extramedullary spinal tumors were managed through excision with total laminectomy approach. This approach will facilitate proper visualization for the surgeon.…”

“…One example of an intraspinal tumor is Intradural-Extramedullary (IDEM) Spinal Tumor. 1 This type is relatively common for tumors in the spinal canal account for about 40%. The most common pathological types for IDEM are a meningioma, schwannoma, and neurofibroma.…”

“…The most common pathological types for IDEM are a meningioma, schwannoma, and neurofibroma. [1][2][3] The most effective management for spinal tumors achieved by total laminectomy. Total laminectomy is one of the conventional technique for removing spinal tumors, and this approach still found commonly.…”
