Introduction: The primary and definitive diagnosis of meningioma is based on histological assessment; however, employing imaging methods, like Magnetic Resonance Imaging (MRI) is very helpful to describe lesion’s characteristics. Accordingly, we decided to study the effect of imaging factors, like MRI data on the volume of hemorrhage (estimated blood loss) during meningioma surgery. Methods: T...

Meningioma is well known as common disease of the central nervous system, whereas primary extracranial meningioma is rare, representing 1% to 2% of all meningiomas. We have experienced a case of primary extracranial meningioma presenting as a right cheek mass. The tumor was completely excised via a right lateral rhinotomy incision. Histopathologic examination confirmed the diagnosis of primary ...

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...

BACKGROUND: Different data exist regarding long-term visual prognosis associated with suprasellar meningiomas. The aim of this study was to determine the outcome of suprasellar meningiomas with respect to short and long-term visual outcomes. METHOD: During the period of 1997 to 2006, 45 patients were operated either through a pterional (30) or bifrontal (15) approach. Visual parameters were eva...

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...

We present a case of nasopharyngeal teratoma that was discovered in association with a suprasellar heterotopic cerebellum in a newborn. Well-differentiated, heterotopic, cerebellar masses have been reported in the orbits, spine, and frontal encephalocele but not, to our knowledge, in the suprasellar region. In this report, we describe the imaging findings and discuss the possible origins of the...
