BACKGROUND let-7d has been indicated to act as a tumor suppressor in various cancers. However, the function and molecular mechanism of let-7d in meningioma progression have not been elucidated. MATERIALS AND METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to detect the expression levels of let-7d and AEG-1 mRNA in meningioma tissues and cell lines. The protein...

Meningiomas are by far the most common tumors arising from the meninges. A myriad of aberrant signaling pathways involved with meningioma tumorigenesis, have been discovered. Understanding these disrupted pathways will aid in deciphering the relationship between various genetic changes and their downstream effects on meningioma pathogenesis. An understanding of the genetic and molecular profile...

Xanthomatous meningioma is an extremely rare variant of meningioma that is characterized histopathologically by the presence of tumor cells with lipid-filled vacuolated cytoplasm. In this report, we describe the fifth documented case of xanthomatous meningioma and review its clinicopathological features. A 76-year-old Japanese male presented with dizziness. Magnetic resonance imaging demonstrat...

BACKGROUND The distinction between meningioma, schwannoma and solitary fibrous tumour/ hemangiopericytoma can be challenging in some cases. This study evaluates the expression of Somatostatin receptor 2A (SSTR2A) and Claudin-1 in these different tumours. MATERIAL AND METHODS Thirty-five cases of meningioma, 10 cases of intracranial schwannoma and 10 cases of hemangiopericytoma were assessed. ...

SUMMARY Ten cases of cystic meningioma are reported and the literature is reviewed. The cyst formation with meningioma is rarely seen and are frequently associated with glial or metastatic tumor. The computerized tomography appearance of our cases also resembling glial and metastatic appearance of our cases also resembling glial and metastatic tumor. The incidence of microcystic and cystic cha...

Meningioma is not uncommon case; however, the differentiation of high-grade from low-grade meningioma important. The rate recurrence grade I 7-20%, but in II 30-40% and III 50-80%. Non-invasive MRI techniques that can differentiate meningiomas before surgery are useful for surgical planning subsequent treatment. We present a review article some case studies (WHO I) III) with conventional contin...

A 38 year old man presented with a hepatic mass which biopsy showed to be a metastasis from an intracranial meningioma. The meningioma originally followed cranial radiotherapy. Previous reports of extracranial metastases are reviewed.

We describe a patient with radiation-induced meningioma 12 years after cranial irradiation for ectopic germinoma. PET scans with fludeoxyglucose F 18 showed a high glucose metabolic rate in the meningioma despite a benign histologic appearance.

Background. The most common intracranial neoplasms worldwide is meningioma. It has been classified into three grades by World Health Organization (WHO) in which each grade several histological variants. prognosis of meningioma affected many factors including histopathological type tumor, age, and gender.
 Objective. aim this study to determine the frequency based on type, gender from 2016 ...

Intracranial meningioma is a rare tumour in children. In Cushing and Eisenhardt's book (1938) on meningiomas, six occurred in the pre-adolescent age group. A review of the literature found six patients to be under 2 years of age with only one survival (Stern, 1937; Bailey, Buchanan, and Bucy, 1939; Grant, 1947; Cuneo and Rand, 1952). The present report concerns a case of giant meningioma succes...
