Meningiomas are mostly benign tumours originating from the arachnoid cap cells, represent 13-26% of all intracranial tumours. They are more common in older age and in females. Deletion in NF2 gene and exposure to ionizing radiation are established risk factors, while the role of sex hormones is...
11K The human nervous system can be susceptible to tumors. Understand growths on the body, the different kinds of nervous system tumors such as gliomas and meningiomas, what causes these tumors to occur, what they do to the body, and how they are diagnosed and treated. Related...
Pituitary adenomasare common benign tumors that grow in the sella turcica, where the pituitary glandsits, and near where the optic nerves travel from the eyes to the occiput in the back of the brain. As the tumor grows, it can push on the optic nerveand cause visual changes andblindness....
123 Accesses Explore all metrics Abstract Survivin, an inhibitor of apoptosis, is over-expressed in foetal tissues and human cancers, but it is almost undetectable in normal tissues. Here we have assessed the level of the survivin protein in some benign tumors of the nervous system: meningioma,...
A modified protein in benign-appearing meningiomas can reveal which are truly benign and which are more dangerous and require more aggressive treatment, researchers have discovered.
Early recurrences in histologically benign/grade I meningiomas are associated with large tumors and coexistence of monosomy 14 and del(1p36) in the ancestr... D. Tabernero, "Early recurrences in histologically benign/grade I meningiomas are associated with large tumors and coexistence of monosomy ...
Rockhill et al.‘s study also showed this pattern in benign meningiomas. Moreover like our study this study confirmed sphenoid ridge as the third site of involvement for all histological type [18]. The most important limitations of this study were: a. This was a retrospective and ...
Sellar and parasellar masses (craniopharyngioma, meningioma, or pituitary adenoma), optic nerve sheath meningiomas and metastatic lesions are included in the differential diagnosis. The other causes related to intracranial pathologies include hypophysis tumours, meningiomas, craniopharyngiomas and aneurisms [...
The second case illustration was the ventral brainstem tumor arisen years after radiation therapy to the neck and parotid region for extracranial meningiomas (Figure 19A). The surgery was done under GA and endoscopic true endonasal transphenoidal transclival approach was used to debulk the tumor (...
The article provides a comprehensive overview of imaging techniques and associated findings for frequent skull base tumors, including meningiomas, and their use in guiding surveillance and treatment decisions.An increase in the accessibility of cranial imaging has resulted in a heightened incidence of ...
