الوصف: Introduction: Dumbbell schwannoma complicated by intradural lumbar disc herniation at the same level is extremely rare. Case presentation: We describe a 67-year-old female presented with low back pain for 10 years and weakness and numbness of the right lower extremity for one month. Contrast magnetic resonance imaging (MRI) revealed an inhomogeneous enhanced dumbbell lesion at the L4/5 right intervertebral foramen and the intradural part of the lesion is only annular enhanced. A single posterior-approach surgery, including L4 laminectomy and right L4/5 facet joint resection, intracapsular resection of extradural dumbbell tumor, and intradural nucleus pulposus resection, was performed. The patient's back pain and weakness of right lower extremity disappeared. Histological studies revealed a schwannoma and a herniated disc. Conclusions: To our knowledge, this case is the first report of dumbbell schwannoma complicated by intradural lumbar disc herniation. Contrast MRI is helpful in preoperative differential diagnosis. Careful preoperative images reading are important to prevent misdiagnosis. Keywords: Dumbbell schwannoma, Intradural disc herniation, Resective surgery

الوصف: Background To evaluate the clinical characteristic, microsurgical treatment and outcomes of patients with multi-segment intramedullary cervical spinal cord tumors (MSICCT). Materials and methods Prospective single center cohort study. 63 patients underwent microsurgery for MSICCT. Pre and postoperative function were assessed using the modified McCormick's grade, IJOA scoring system, and analyzed using the appropriate statistical tests. Results 41 males, 22 females, three spinal segments were involved in 22(35%) cases, four or more in 41(65%) of cases. Majority of the tumors were ependymoma (54%), followed by astrocytoma (low grade 25%, high grade 8%). McCormick's grade: I&II in 40 patients (64%). There was no statistical difference between preoperative and three-month postoperative IJOA scores (P = 0.76), indicating no significant neurological deterioration after surgery. The extent of surgical resection was highly correlated to histological tumor type of MSICCT (χ2 = 34.82, P = 0.0001) and three-month postoperative IJOA scores (F = 2.62, P = 0.006). There is a high proportion of total resection in ependymomas, haemangioblastomas, cavernomas and schwannoma, whereas, we only achieved partial resection in most gliomas. With a mean follow up of 5.5 years (3 months–more than 12 years), clinical outcome improved or stabilized in 91% of cases (80% improved, 11% stabilized, 9% deteriorated). Conclusion This series of MSICCT showed that high extent of surgical resection could be achieved in most ependymomas with good long-term outcome. Astrocytomas, in contrary remained challenging with 25% achieved gross total resection. Overall, compared to previous surgical series, we showed encouraging improvement in the clinical outcome of these patients managed surgically.
