  • The incidence of spinal meningioma is very rare in children. A 14-year-old girl presented with right arm weakness, gait disturbance, and urinary incontinence. Cervical magnetic resonance imaging revealed an intradural extramedullary tumor dorsal to the spinal cord in the level of C1. The tumor was totally removed despite the severe cord compression. Meningotheliomatous meningioma was diagnosed after histological examination.

  • Capillary hemangiomas are common soft tissue tumors on the skin or mucosa of the head and neck in the early childhood, but very rare in the neuraxis. A 47-year-old man presented with one month history of back pain on the lower thoracic area, radiating pain to both legs, and hypesthesia below 17 dermatome. Thoracic spine MRI showed $1{\times}1.3{\times}1.5\;cm$, well-defined intradural mass at T6-7 disc space level, which showed isointensity to spinal cord on T1, heterogeneous isointensity on T2-weighted images, and homogeneous strong enhancement. The patient underwent T6-7 total laminotomy, complete tumor removal and laminoplasty. Histologically, the mass showed a capsulated nodular lesion composed of capillary-sized vascular channels, which were tightly packed into nodules separated by fibrous septa. These features were consistent with capillary hemangioma.

  • Intradural extramedullary (IDEM) ependymomas occur very rarely and little has been reported about their clinical characteristics. The authors present a case of a 57-year-old woman with an IDEM ependymoma. She was referred for the evaluation of a 4-month history of increasing neck pain and muscular weakness of the left extremities. Magnetic resonance imaging (MRI) of the cervical spine demonstrated an IDEM tumor with spinal cord compression. At the time of surgery, an encapsulated IDEM tumor without a dural attachment or medullary infiltration was noted, but the tumor capsule adherent to the spinal cord and root was left in place to minimize the risk of neurological sequelae. Histologic examination revealed a benign classic ependymoma. The post-operative course was uneventful and radiotherapy was performed. The patient showed an excellent clinical recovery, with no recurrence after 5 years of follow-up.

  • Intradural extramedullary hemangioblastoma of the spinal cord is uncommon tumor. Symptom onset is typically in the forth decade. Complete excision offers the best chance for cure. We report a case of extramedullary hemangioblastoma of the spinal cord in old age. A 76 -year old man presented with 1 month history of paraparesis. Multiple enhancing lower thoracic and lumbar spinal masses were seen on magnetic resonance imaging(MRI). Surgical exploration for symptomatic lesion revealed intradural-extramedullary mass, which had hypervascularity. The excised spinal masses were diagnosed as hemangioblastoma. Postoperative course was uneventful and symptoms improved gradually.

  • Mesenchymal chondrosarcomas are rare malignant tumors of the bone and soft tissue. Spinal mesenchymal chondrosarcomas are even rarer and, to the best of our knowledge those that are concomitantly located in the intradural and extradural regions, have never been reported. We report a case of a 25-year-old man with back pain and bilateral progressive weakness of the lower extremities. Magnetic resonance imaging revealed a markedly enhanced dumbbell-shaped mass at the T7 level. The lesion was intradurally located at the left side of the spinal cord, and extended extradurally to the extraforminal space through the T7-8 intervertebral foramen. The tumor was completely excised through a posterior approach. Microscopic examination and immunohistochemical studies confirmed mesenchymal chondrosarcoma. Postoperative radiation therapy and chemotherapy were also performed to prevent local recurrence and metastasis. The patient has been symptom-free for two years after surgery. Herein, we reviewed and discussed the clinical characteristics, treatments, and outcomes of primary intraspinal mesenchymal chondrosarcomas in the literature.

  • Primary central nervous system (CNS) melanoma is a rare condition that accounts for only 1% of all melanomas. A 34-year-old Korean female presented with a two-month history of progressive weakness in both legs. Spinal magnetic resonance image (MRI) revealed a spinal cord tumor at the level of T4, which was hyperintense on T1-weighted imaging and hypointense on T2-weighted imaging. The intradural and extramedullary tumor was completely resected and diagnosed as melanoma. There were no metastatic lesions. At three years after surgery, the patient is still alive, with no evidence of tumor recurrence. We present the details of this case along with a comprehensive review of spinal cord melanoma.

  • Primary melanotic schwannoma in spinal cord is a very uncommon disorder, eight cases of melanotic schwannoma in spinal cord have been found in the literature. We present a case report of a patient with an intradural, extramadullary melanotic schwannoma in cervical spine and the literature on melanotic schwannoma is reviewed. The proposed theories on the origin of these tumors and treatment are discussed.

  • Most extracranial schwannomas are solitary, but neurofibromas are frequently associated with other manietations of neurofibromatosis. Schwannomas that occur within the context of neurofibromatosis tend to be multiple, but multiple schwannomas without manifestation of neurofibromatosis type 2 are very rare. The authors report a very rare case of multiple spinal intradural schwannomas in the absence of neurofibromatosis Type 2 maniestations. A 40-year-old man suffered from longstanding low back pain and left side sciatica which was treated with two stage operations. MRI showed multiple intradural mass lesions extending from L1 vertebral segment to S1 vertebral segment. There were no clinical and radiological manifestations of Type 2 neurofibromatosis. Histologically confirmed diagnosis was schwannoma.

  • The authors report a case of 42-year-old woman with an intraventricular tumor in the trigone of the left lateral ventricle. The first operation achieved a microscopically complete resection. The tumor was histologically atypical meningioma. After 26 months, there were recurrences of intraventricular meningioma. Complete resection of the tumor and adjuvant radiation therapy were performed, and the histological diagnosis was malignant meningioma. Sixteen months after the second operation, spinal metastasis in cervicolumbar lesion was diagnosed and a subtotal removal of cervical intradural extramedullary mass was performed. We describe an unusual case of intraventricular malignant meningioma with cerebrospinal fluid-disseminated spinal metastases with review of the clinical courses of previous reports.

  • Objective : The spinal cord tumors(including vertebral tumors) are increasingly diagnosed and operated due to development of refined diagnostic and therapeutic tools. It is necessary to re-evaluate clinical features and surgical results of spinal cord tumors with increasing cases and developing treatment modalities. The authors reviewed the spinal cord tumor cases to evaluate their clinical characteristics. Material and Methods : The retrospective review of 654 cases of spinal cord tumors between 1973 and 1999 was done. The clinical features, pathological analysis and surgical results were analyzed and compared to the literature. The results of the study are analyzed with a more detailed consideration of each of major pathologies : neurogenic tumors, meningeal tumors, neuroepithelial tumors, and metastatic tumors. Results and Conclusion : The spinal cord tumor was most common in the 5th decade of age(145 cases, 22.1%) and 78 cases(11.9%) were found in children under 15 years of age. The ratio of male to female was 1.2 : 1. The pathologic diagnosis was neurogenic tumor in 266 cases(40.7%), neuroepithelial tumor in 131(20.0%), metastatic tumor in 118(18.0%), and meningeal tumor in 94(14.4%) in the order of frequency. The tumor was located most frequently in the thoracic area(36.5%) and in the intradural extramedullary space(38.1%). The most common initial presentation was pain(40.1%) and the mean duration for presentation to operation was 14.8 months. The total or gross total removal was possible in 404 cases(61.7%) and the surgical result on the postoperative one month was recovery or improvement in 424 cases(64.8%), stationary in 188(28.7%), progression in 42(6.4%). As a surgical complication, there was a spinal deformity(12 cases), wound infection(5 cases), aspiration pneumonia(5 cases) etc. Neurogenic tumors and menigiomas showed good surgical results, whereas neuroepithelial tumors(except ependymoma) and metastatic tumors showed relatively poor prognosis.
