Meningioma is the commonest primary intracranial tumor in adults, with majority being benign. Malignant meningioma exceedingly rare and carries a poor prognosis because of its tendency for local recurrence distant metastasis. We present case 53 years old male anaplastic malignant meningioma, which recurred after excision radiotherapy later metastasised to pleura, bones brain. Keywords: Metastat...

Meningioma recurrence after complete removal remains one of the most relevant problems of meningioma treatment. DNA microarray technologies allow the screening of several thousands genes simultaneously. This gene expression profiling approach has been successfully applied in many researches associated with tumor classification. We analyzed genome wide expression profiles of 68 meningioma sample...

BACKGROUND The etiology of meningioma is largely unknown, although breast cancer has been suggested to play a role. METHODS A monoinstitutional, retrospective analysis was performed at European Institute of Oncology on 12,330 patients with breast cancer. The cumulative incidence of meningioma was estimated using the Kaplan-Meier method and the log-rank test was used to assess differences betw...

purpose: to report an unusual case of orbitocranial meningioma presenting in a neonate. methods: case report results: a 1-day-old neonate was presented with severe proptosis of the left eye. ct scan and mri showed an extensive mass with involvement of left orbit and brain. discrete calcification could be seen on ct scan. the patient did not have any signs of neurofibromatosis and family history...

Differential diagnosis of a solid cystic lesion in supratentorial location includes glioma,1 meningioma,2 metastatic tumor,3 or hemangioblastoma.1 Cystic meningioma is relatively a rare tumor.2 Among various histological variants of meningioma, the meningothelial type most frequently demonstrates cystic changes.3 Richly vascularized meningiomas of the angiomatous type were reported only in a fe...

The 5-aminolevulinic acid (5-ALA)-induced tumor fluorescence is a useful intraoperative marker for the diagnosis and the detection of various malignancies, but its use in meningioma is only reported infrequently. In meningioma, a complete resection of the tumor mass is crucial for the prevention of recurrence and postoperative morbidities. Deep sylvian meningioma is a rare type of meningioma wh...

The authors present a case of familial clear cell meningioma in which the proband is a child with an intraspinal tumor. The clear cell meningioma variant has recently been studied. The literature regarding clear cell meningioma is reviewed.

OBJECTIVE A rare subtype of meningioma, sclerosing meningioma is not included in the current World Health Organization classification of meningiomas and is classified into the category of other morphological variation subtypes. Sclerosing meningioma is often misdiagnosed to other non-benign meningioma or malignant neoplasm, so it is important to diagnose sclerosing type correctly. We analyzed t...

Since the atomic bomb explosions in Hiroshima and Nagasaki, high incidences of leukemia, thyroid cancer and other tumors have been reported as atomic bomb-induced tumors. We investigated the incidence of meningioma among Hiroshima atomic bomb survivors. Sixty-eight patients surgically treated for meningioma who had been within 2.0 km of the hypocenter of the explosion were identified. Six hundr...

Ionizing radiation is the most established risk factor for meningioma formation. Our aim was to evaluate the main effect of selected candidate genes on the development of meningioma and their possible interaction with ionizing radiation in the causation of this tumor. The total study population included 440 cases and controls: 150 meningioma patients who were irradiated for tinea capitis in chi...
