1/113. Multiple spinal meningiomas--a case report.Multiple spinal meningiomas are relatively rare and account for only 2 to 3.5% of all spinal meningiomas. A case of multiple meningiomas of the thoracic (T) spine was reported. This 77-year-old woman was admitted with progressive motor weakness and sensation disturbance in both legs for 4 months. Neurological findings on admission revealed paraparesis, hyperesthesia, and hypalgesia below the dermatome of T10 level and hyporeflexia of both ankles. Urinary and stool incontinence were also noted. magnetic resonance imaging (MRI) documented two intradural extramedullary lesions with different intensity at the T9 and T12 levels. Both tumors were totally resected. Histopathologic examination showed all psammomatous meningiomas with more or less psammoma bodies. There were no any manifestations of von Recklinghausen's disease in this patient. MRI is a choice of diagnostic tool to detect spinal tumors, especially multiple spinal meningiomas. Different intensities in MRI may infer different components of meningiomas. Follow-up study after operation three months later disclosed she could walk very well.- - - - - - - - - - ranking = 1keywords = meningioma, meningiomas (Clic here for more details about this article) |
2/113. Solitary fibrous tumor of the spinal cord. Report of a case with scrape cytology.BACKGROUND: Solitary fibrous tumor is a rare spindle cell tumor and has been forced at a variety of sites. To the best of our knowledge, only two cases of solitary fibrous tumor arising in the spinal cord have been reported; no cytologic findings were documented. CASE: A 62-year-old male presented with a spinal cord tumor. A scrape smear of the resected tumor revealed naked, spindle-shaped nuclei. Some nuclei were twisted or had long spindles. In the background, abundant, thin and thick collagen fibers were present. Immunohistochemically, the spindle cells were positive for CD34 and negative for S-100 protein and alpha-smooth muscle actin. Histologic diagnosis of the tumor was benign solitary fibrous tumor. CONCLUSION: Our case indicates that solitary fibrous tumor can occur in the spinal cord and should be differentiated from other benign spindle cell tumors, such as meningioma and schwannoma. The key cytologic features of solitary fibrous tumor may be the presence of abundant thin and thick collagen fibers in scrape specimens.- - - - - - - - - - ranking = 0.087052576841301keywords = meningioma (Clic here for more details about this article) |
3/113. Development of postoperative fibromatosis after resection of an intraspinal meningioma. Case report.The authors report the case of an adult female patient who developed a paraspinous thoracic fibromatosis (desmoid tumor) after undergoing resection of an intraspinal thoracic meningioma that was complicated by postoperative wound infection. To the best of the authors' knowledge, this is the first report of such a tumor occurring after resection of a spinal meningioma. awareness of the development of postoperative fibromatosis and recognition of its association with wound sepsis is important. Although rare, this distinctive lesion should be considered in the differential diagnosis of the apparent rapid regrowth of otherwise indolent lesions including meningioma.- - - - - - - - - - ranking = 0.60936803788911keywords = meningioma (Clic here for more details about this article) |
4/113. Spinal cartilaginous meningioma in a child: a case report.cartilage-containing meningiomas are extremely uncommon, and such tumors located in the spinal cord of a child have not previously been reported. We describe a case of cartilaginous spinal meningioma in a 13-year-old girl. The tumor lacked typical histopathological features of meningioma on light microscopic examination, and the final diagnosis was possible only after an extensive study by electron microscopic examination. The case is evaluated with a focus on differential diagnosis and review of the literature.- - - - - - - - - - ranking = 0.62231546104781keywords = meningioma, meningiomas (Clic here for more details about this article) |
5/113. Post-radiotherapy myelitis observed in an AIDS patient with a meningioma: case report and review of the literature.radiation myelitis is an uncommon but serious complication of radiation therapy. Although the definitive threshold to cause myelitis is unknown, it is believed that less than 50 Gy when given in 25 or more fractions is highly unlikely to cause myelopathy. This report describes a case of myelitis within the radiotherapy portal in an hiv infected patient who received radiation therapy for an atypical meningioma located in the cervical spine. A complete resolution of the meningioma was also noted in this case. The possible contributing roles of hiv infection and concomitant administration of antiviral drugs are discussed.- - - - - - - - - - ranking = 0.52231546104781keywords = meningioma (Clic here for more details about this article) |
6/113. Extradural meningioma en-plaque of the cervical cord.A rare case of cervical extradural en-plaque meningothelial meningioma is reported. The magnetic resonance imaging revealed an extradural sheet of tumor encasing the cervical cord from anterior, posterior and right lateral aspects and emerging from the right C3-4 intervertebral foramina. Though a differential diagnosis of lymphoma and tubercular granulation tissue were considered, its isointense intensity patterns on T1 and T2 weighted images and the intratumoral calcification on intrathecal contrast computed tomographic scan suggested a meningioma. At surgery, the lesion was fibrous, avascular and densely adherent to the dura. The radiological features and management options of the lesion are discussed.- - - - - - - - - - ranking = 0.52231546104781keywords = meningioma (Clic here for more details about this article) |
7/113. Spinal papillary meningioma: a case report and review of the literature.A rare case of a spinal papillary meningioma in a 19-year-old adolescent is described. Six months after radical resection the patient showed dissemination along the cerebrospinal pathway. Papillary meningiomas are rare tumours with a relatively high incidence in childhood. Most papillary meningiomas reported in the literature are considered as aggressive variants of meningioma with often local recurrence, dissemination in the CSF and metastases to remote sites. This case supports that, although the histogenesis remains unexplained, papillary meningiomas deserve recognition on the basis of their high morbidity and mortality.- - - - - - - - - - ranking = 0.82231546104781keywords = meningioma, meningiomas (Clic here for more details about this article) |
8/113. Intraspinal clear cell meningioma: diagnosis and management: report of two cases.OBJECTIVE AND IMPORTANCE: Intraspinal clear cell meningioma is a rare morphological variant of meningioma. Only 13 case reports are found in the literature; therefore, no management strategy has been defined for this tumor type. This article describes two patients, reviews the literature, and proposes a treatment plan for clear cell meningioma. CLINICAL PRESENTATION: Two female patients, 22 months and 8 years of age, respectively, presented with localized neck and leg pain that limited their ability to walk. magnetic resonance imaging revealed intradural tumors, a cervical intramedullary neoplasm in the younger patient, and a cauda equina tumor in the older child. INTERVENTION: Both patients underwent radical resection of their intradural tumor. Both tumors, however, recurred shortly (5 and 6 mo) after the initial operation. During the second operation, a radical removal was performed on each patient. Both patients received adjuvant radiotherapy. In addition, the younger patient developed posterior fossa metastasis 20 months after intraspinal surgery. CONCLUSION: Intraspinal clear cell meningiomas are very uncommon tumors. The clinical course in our two patients supports the reported 40% recurrence rate within 15 months. These tumors also can disseminate within the central nervous system. We recommend serial imaging studies every 3 months. For recurrent tumors, we recommend localized radiation therapy after reoperation.- - - - - - - - - - ranking = 0.70936803788911keywords = meningioma, meningiomas (Clic here for more details about this article) |
9/113. Recurrent calcified spinal meningioma detected by plain radiograph.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.- - - - - - - - - - ranking = 1.1575783452543keywords = meningioma, meningiomas (Clic here for more details about this article) |
10/113. Tanycytic ependymoma in association with neurofibromatosis type 2.A rare case of tanycytic ependymoma associated with neurofibromatosis type 2 (NF2) is presented for the first time, with emphasis on its clinical course and histopathological features. A 30-year-old man had developed gait disturbance in his childhood, and harbored multiple tumors in spinal nerve roots, in the intradural extramedullary and intramedullary spinal cord. The spinal root tumor and intradural extramedullary tumor were histologically diagnosed as schwannoma and meningioma, respectively. magnetic resonance imaging showed two intramedullary cystic lesions, one in the cervical and the other in the thoracic spine. Because his sensorimotor dysfunction in the lower extremities continued to worsen gradually, three of the multiple nodular tumors in the thoracic cystic lesion were removed. All three tumors were composed of eosinophilic piloid cells with modest nuclear pleomorphism. No Rosenthal fibers were found. A concentration of slender eosinophilic cellular processes surrounding the vascular wall was seen. periodic acid Schiff and Masson trichrome-positive balloons were seen in the extracellular space. Detection of ependymal rosettes, although only few in number, led the diagnosis as a tanycytic ependymoma. Recognition of this ependymoma variant should be emphasized to avoid confusion with pilocytic astrocytoma or intramedullary schwannoma.- - - - - - - - - - ranking = 0.087052576841301keywords = meningioma (Clic here for more details about this article) |
