Meningiomas are extraaxial central nervous system tumors most often discovered in middle to late adult life, and are more often seen in women. Ninety percent of meningiomas are benign, 6% are atypical, and 2% are malignant. Most patients in whom a meningioma is diagnosed undergo resection to relieve neurological symptoms. Complete resection is often curative. For the majority of incompletely re...

Meningiomas presenting as an intracranial neoplasm are relatively common. (15–18%).However, primary extracranial (ectopic, extracalvarial) meningiomas of the ear and temporal bone are rare, making up for less than 1% of all meningiomas. 1 The known female preponderance of intracranial meningiomas is also seen in the external auditory canal meningioma. They may be primary (very rare) or secondar...

Background: to present personal experience in the surgical management of spinal meningiomas, also the literature results review too. Methods: 32 patients (4 men and 28 women) harboring spinal meningiomas who had undergone microsurgical resection were treated between 2002 and 2012 in our department. Clinical presentation, diagnosis, histological examination, microsurgical resection, functional o...

Meningioma is a prime example of a tumor requiring a multimodality approach. This tumor is usually benign and often grows slowly. Under many circumstances, such a benign tumor would never attract the attention of the oncologist or even require treatment at all. However, a meningioma is a benign tumor in a malignant location. In the closed space of the skull, there is no room for expansion of ev...

Meningiomas are brain tumors that originate from arachnoid cap cells. They account for about one third of all brain tumors (CBTRUS, 2011), and their incidence increases with age. There are many histological subtypes of meningioma and they differ in their level of malignant behavior. The most commonly used World Health Organization (WHO) scheme (see 2.1) classifies them in three grades, which ha...

Three cases of intracranial dural chondrosarcoma are reported. The radiologic appearance of this slow-growing, extraaxial malignant tumor is different from the more familiar skull-base chondrosarcoma and may mimic an atypical meningioma. Dural chondrosarcoma tends to be less calcified or even to lack matrix calcification; it is associated with bone erosion but not with bone destruction or hyper...

We describe herein a patient with primary intracerebral malignant fibrous histiocytoma (MFH) to demonstrate this very rare central nervous system tumor. A 42-year-old male was admitted to our institute with the complaints of headache and speech impairment. Magnetic resonance imaging (MRI) revealed a tumor consistent with meningioma and we decided the surgery. The tumor was excis...

Extradural spinal meningiomas are rare. Our understanding of purely extradural spinal meningiomas is still incomplete and they may be easily confused with malignant neoplasms, much more common in this location. We report a rare case of a purely extradural thoracic spine meningioma in a 70-year-old man, with an unusual progression. In addition we discuss the pathogenesis of these tumors and the ...

Anaplasia is defined by morphologic features of frank malignancy exceeding those present in atypical meningioma. Those features include obvious malignant cytomorphology (resembling carcinoma, melanoma or sarcoma), or a high mitotic index with more than 20 mitoses per 10 high-power fields [1]. Anaplastic meningiomas exhibit an aggressive clinical course including rapid growth, local recurrence, ...
