Ventricular schwannomas are very uncommon. We report such a tumor in the right lateral ventricle of a 16-year-old young man. The various etiopathogenic hypotheses are discussed.

Internet has become the first place where patients go to when seeking information about their disease. Little is known about the type and the quality of the medical information available on French-speaking websites, especially in the field of neuro-oncology. The purpose of this study was to evaluate the quality of these sites. ⋯ This study shows that the search for medical information on the Internet is time consuming and often disappointing: very few websites provide information that is both clear and exhaustive. However, we also found that very few websites contained information that was seriously inaccurate. Given the growing popularity of the Internet, patients could certainly benefit from a high quality French speaking website that would specialize in cerebral tumors, as well as from a neuro-oncological portal that would take them to selected websites as it would save time and would be a guarantee for quality.

Optic nerve sheath meningioma (ONSM) accounts for one-third of primary optic nerve tumors, and 2% of all meningiomas. ONSM must be distinguished from other meningiomas, in particular from cavernous meningiomas because of the different prognosis and treatment. The most frequent clinical sign is a progressive or sudden unilateral visual loss. Treatment of ONSM is still subject to discussion. This report covers a series of eight ONSM patients treated with fractionated stereotactic radiotherapy. ⋯ This is still a preliminary study, but the results suggest that fractionated stereotactic radiotherapy may emerge as a primary treatment for ONSM, delaying surgery, which has proven functionally disappointing.
