Abstract
While intradural extramedullary spinal disease varies widely, identification of tumors in this location and their radiologic manifestations greatly facilitates narrowing of the diagnostic considerations. Meningioma and schwannoma are the two most common intradural extramedullary tumors, and both are associated with neurofibromatosis. Meningiomas are most common in the thoracic spine and show a strong female predilection and a clinical manifestation related to compression of the spinal cord or nerve roots. Schwannomas typically are associated with radicular pain and other sensory symptoms. Melanotic schwannoma frequently shows T1 hyperintensity at MRI related to the presence of paramagnetic free radicals in melanin. Neurofibroma, known for its T2 hyperintensity, frequently involves the cervical spine, where it may make surgical resection challenging. Less commonly, malignant peripheral nerve sheath tumor commonly mimics the imaging appearance of a schwannoma but has decidedly more aggressive biologic behavior. In the cauda equina, myxopapillary ependymoma and paraganglioma are believed to arise from the filum terminale and have characteristic imaging manifestations based on their underlying pathologic features. Recent identification of a common genetic marker has led to reclassification of what had previously been regarded as separate tumors and are now known as solitary fibrous tumor/hemangiopericytoma. In the proper clinical setting, the presence of nodular intradural enhancement strongly suggests the presence of leptomeningeal metastatic disease, even when results of cerebrospinal fluid analysis are negative. This article highlights the characteristic neuroimaging manifestations of these neoplasms, with emphasis on radiologic-pathologic correlation. See Illumination by Frazier .

[PMID: 25983821 PMCID: PMC4431008 DOI: 10.14245/kjs.2012.9.3.232] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/13/2012] [Revised: 09/04/2012] [Accepted: 09/26/2012] [Indexed: 11/19/2022]
Abstract
Objective To reduce the risk of postoperative spinal instability or deformity, unilateral laminectomy (UL) has been recommended to remove spinal space-occupying lesions. The purpose of this study was to determine whether there were any advantages of UL for removal of spinal cord tumors. Methods From May 1995 to May 2010, 94 patients with spinal cord tumors, who underwent tumor removal via UL in our institute, were enrolled in this study. Intramedullary spinal cord tumors were excluded. Simple radiographs were obtained for accessing the restoration of the spinal column. Spinal magnetic resonance imaging (MRI) was also obtained during the follow-up period to evaluate tumor recurrence. Results There were 51 women and 43 men; their mean age was 47.8 years (range, 9-83 years). The mean follow-up period was 52.6 months (range, 24 month-16 years). The sites of the tumors were cervical in 21 cases, thoracic in 37, lumbar in 33, and sacral in 3. These cases included 85 intradural extramedullary (IDEM) and 9 extradural (ED) lesions. IDEM tumors consisted mainly of neurilemmomas (56.3%) and meningiomas (22.3%).Tumors were totally removed in 80 cases and subtotally removed in 14 cases. Postoperative neurological status was improved in 53 cases, unchanged in 31 cases, and worsened in 10 cases. During follow-up, MRI showed tumor recurrence in 4 patients. Histopathologically, three cases were meningiomas and one case was neurilemmoma. None of the patients showed spinal instability or kyphotic deformity at last follow-up. Conclusion UL is an optimal approach for providing sufficient exposure of spinal cord tumors without development of postoperative spinal instability and regional sagittal imbalance in any location of spinal column. In cases of meningioma, careful long-term follow up is needed due to it's relatively high recurrence rate after removal via UL.

Abstract
Meningiomas are the second most common intradural spinal tumors accounting for 25% of all spinal tumors. Being a slow growing and invariably benign tumor, it responds favorably to surgical excision. In addition, spinal meningioma has low recurrence rates. However, we experienced a case of intradural extramedullary spinal meningioma which recurred 16 years after the initial surgery on a 64-year-old woman. She presented with progressive neurological symptoms and had a surgical history of removal of thoracic spinal meningioma 16 years ago due to bilateral low leg weakness. She underwent a second operation at the same site and a pale yellowish tumor was excised, which was histopathologically confirmed as meningothelial meningioma, compared with previously transitional type. she showed neurological recovery after the operation. We, therefore, report the good results of this recurrent intradural spinal meningioma case developed after 16 years with literature review.

Abstract
OBJECTIVE The advantages of a posterior "conventional" suboccipital approach with a midline incision over lateral, anterolateral, and anterior approaches to anteriorly placed foramen magnum meningiomas are discussed. METHODS From 1991 to March 2000, 17 patients with foramen magnum meningiomas arising from the anterior or anterolateral rim of the foramen magnum underwent operations in the Department of Neurosurgery at King Edward Memorial Hospital and Seth G.S. Medical College. All patients were operated on in a semi-sitting position by use of a conventional suboccipital approach with a midline incision and extension of the craniectomy laterally toward the side of the tumor up to the occipital condyle. RESULTS The patients ranged in age from 17 to 72 years, and the tumors ranged in size from 2.1 to 3.8 cm. The intradural vertebral artery was at least partially encased on one side in eight patients and on both sides in two patients. The brainstem was displaced predominantly posteriorly in each patient. A partial condylar resection was performed in two cases to enhance the exposure. Total tumor resection was achieved in 14 patients, and a subtotal resection of the tumor was performed in the other 3 patients. In one patient, a small part of the tumor was missed inadvertently, and in the other two patients, part of the tumor in relation to the vertebral artery and posterior inferior cerebellar artery was deliberately left behind. After surgery, one patient developed exaggerated lower cranial nerve weakness. There was no significant postoperative complication in the remainder of the patients, and their conditions improved after surgery. The average length of follow-up is 43 months, and there has been no recurrence of the tumor or growth of the residual tumor. CONCLUSION From our experience, we conclude that a large majority of anterior foramen magnum meningiomas can be excised with a lateral suboccipital approach and meticulous microsurgical techniques.

Abstract
STUDY DESIGN A case report of a patient presenting with a rare calcified spinal meningioma that recurred and became symptomatic 33 years after initial surgery was performed. OBJECTIVES To demonstrate a calcified recurrent spinal meningioma visible on a plain radiograph. The present case is discussed in conjunction with a review of previous cases of calcified spinal meningioma. SUMMARY OF BACKGROUND DATA Meningioma is a common spinal tumor that has a favorable prognosis if resected completely. Microscopic calcification is frequently found in spinal meningiomas because of psammoma bodies. However, calcified meningiomas in the spinal canal that can be detected on a plain radiograph are uncommon. To the authors' knowledge, there have been no previous reports of recurrent spinal meningioma with calcification visible on a plain radiograph. METHODS A patient experienced difficulty in walking and was diagnosed as having a spinal meningioma. Laminectomies and a total tumor excision were performed. Histologically, the tumor was diagnosed as a psammomatous meningioma. The tumor recurred and became symptomatic 33 years after the initial operation. The tumor was detected on a plain radiograph, appearing as a calcified tumor at the same thoracic level as the site of the initial operation. The recurrent tumor was completely removed, and a histologic examination showed huge psammoma bodies with calcification, but without ossification. RESULTS Preoperative paraplegia improved after the surgery, and she was able to walk with a crutch. The patient was discharged from the hospital. CONCLUSIONS The recurrent psammomatous meningioma contained clusters of calcified psammoma bodies, resulting in a hard tumor that was visible on a plain radiograph.

Abstract
Among a series of 782 spinal tumors, 130 spinal meningiomas in 117 patients were operated in the Department of Neurosurgery at the Nordstadt Hospital in Hannover, Germany, between 1977 and 1998. Patients were followed postoperatively for up to 13 years (mean 20 +/- 33 months). Comparing the period of 1977 through 1987, before magnetic resonance imaging (MRI) was available, to the period of 1988 to 1998 revealed that the average history until diagnosis shortened by about 6 months during the second decade of this study (24 +/- 33 to 18 +/- 29 months; not significant). Consequently, the preoperative Karnofsky Score increased significantly (59 +/- 15 and 66 +/- 16; p < 0.05). The rates of complete resection and the postoperative neurological outcome, however, remained unchanged. Even though the overall prognosis of neurological deficits is favorable after complete resection of a meningioma, a subset of 18 patients had either en plaque growing or recurrent tumors that were more likely to be removed incompletely and to cause postoperative neurological problems, with a significantly worse Karnofsky Score after 1 year (57 +/- 12 and 77 +/- 12, respectively; p < 0.01) and a significantly higher recurrence rate after 5 years (86.7% and 20.4%, respectively; log rank test p = 0.0014). In conclusion, a favorable postoperative neurological outcome requires complete resection of the spinal meningioma. The advent of MRI has shortened the time until diagnosis and made it possible to perform surgery before severe deficits have occurred, but did not have a major impact on postoperative results. En plaque and recurrent meningiomas remain surgical challenges, as infiltration of surrounding structures and associated arachnoid scarring may render complete resection difficult to achieve.

Abstract
INTRODUCTION Intraspinal meningiomas account for 25%-46% of primary spinal cord tumors. Technical advances in magnetic resonance imaging (MRI) and surgical procedures (ultrasonic cavitation aspirators [CUSA], lasers) have brought about better clinical results. In spite of these new techniques, a small percentage of patients still present with poor postoperative results and/or a recurrence. The authors tried to determine which data could influence clinical outcome and what therapeutic modalities could limit recurrence rate. MATERIALS AND METHODS We reviewed 54 patients who from 1963 to 1994, each had surgery for an intraspinal meningioma. There were 43 females and 11 males, aged 8 to 85 years old. Thirty-six (66.6%) patients were ambulatory on admission; only 2 presented with a paraplegia. Tumor location was cervical in 10 cases, thoracic in 43 cases, lumbar in 1 case. Forty-seven tumors were intradural, 5 epidural, 2 epidural and intradural. Thirty patients underwent a myelography, 10 a computed tomography (CT) scan, and 14 an MRI. Twenty-three spinal angiographies were performed before surgery. Complete removal was achieved in 50 patients (92.6%). Ultrasonic cavitation was used 10 times for debulking the tumor, and laser was used in 12 surgical procedures to perform hemostasis of the meningioma and to coagulate the dural attachment. RESULTS The majority of the neoplasms were meningothelial (N = 24) or psammomatous (N = 11). No mortality was noted. Morbidity concerned five patients: two pulmonary embolisms, one definitive paraplegia, one transient deficit, and one epidural suppuration, which necessitated a second operation. Mean follow-up was 28 months. Final functional results were very good in 85% and good in 13%; one patient (2%) worsened. Two recurrences were noted: one with clinical signs and the other with only CT-scan modifications. Both patients underwent complementary radiotherapy. DISCUSSION AND CONCLUSION The authors discuss factors influencing functional results. Sex, pregnancy, pathologic diagnosis, and recurrence do not seem to have any influence. Calcification of the meningioma, as well as an anterior dural attachment, are pejorative factors. They insist on preoperative angiography and point out the advantage of using a CUSA and/or a laser to debulk and coagulate the tumor itself and its dural attachment. They propose radiation therapy as an adjuvant treatment or an alternative to reoperation, which could be hazardous for some patients when, for instance, a recurrence is located in a critical area or when the patient's general status is fragile.

Abstract
Syringomyelia is known to occur secondary to compression of the spinal cord. We report the case of a female patient who underwent removal of a spinal meningioma. She re-presented 30 years later with multiple meningiomas causing cord compression. After a 4 year interval she was found to have developed a syrinx proximal to the site of compression. Comparison with previous case reports suggest that the causation of syringomyelia is multi-factorial.

Abstract
The authors present a retrospective analysis of 97 cases of spinal meningioma. Age, sex, tumor location, and clinical presentation are similar to that reported by others. Importantly, even among paraplegic patients, one-third eventually walked. Other findings of note were poor results among those with calcified or recurrent tumors, and a high incidence of invasiveness among the rare epidural lesions. Males do not show the preference for a thoracic location that is found among females, and cervical tumors are almost all anterior to the cord. This last point suggests a different surgical approach in some cases. A large percentage of cases carried other diagnoses before tumor was recognized.
