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...

INTRODUCTION Meningiomas are intracranial brain tumours that frequently recur. Recurrence rates up to 20% in 20 years for benign meningiomas, up to 80% for atypical meningiomas and up to 100% for malignant meningiomas, have been reported. The most important prognostic factors for meningioma recurrence are meningioma grade, meningioma invasiveness and radicality of neurosurgical resection. The a...

Although the etiology of primary brain tumors is largely unknown, prior studies suggest that DNA repair polymorphisms may influence risk of glioma. Altered DNA repair is also likely to affect the risk of meningioma and acoustic neuroma, but these tumors have not been well studied. We estimated the risk of glioma (n = 362), meningioma (n = 134), and acoustic neuroma (n = 69) in non-Hispanic whit...

Data on the association between smoking and meningioma are inconsistent. The aim of this study was to assess the role of smoking in radiation- and non-radiation-related meningiomas. The study was designed as a 4-group case-control study, balanced for irradiation, including 160 irradiated meningioma case patients, 145 irradiated control subjects, 82 nonirradiated case patients, and 135 nonirradi...
