although measurement of intracranial pressure by noninvasive methods has been suggested, but mainly invasive methods are used for this purpose-increase in episcleral venous pressure can be expected to result in a linear increase in intraocular pressure. congested oculat veins with capillary leakage and hemorrhage are seen when the icp is increased, thus theoretically measurement of intraocular ...

Meningiomas represent the most common benign intracranial neoplasms, and may spread by direct extension into nearby venous sinuses, but gross spread to the extracranial venous system is uncommon. We report the case of a patient with extracranial intraluminal spread of meningioma within the internal jugular vein to level III of the neck. Review of the preoperative assessment and management is al...

An unusual case of bilateral intratentorial lipomas with extension into Meckel's caves and the cerebellopontine angle is described. Surgical and histopathologic correlation demonstrate that the lipoma encased the trigeminal nerve in Meckel's caves. The origin of the lipoma from the anteromedial margins of the tentorium is discussed and correlated with a recently proposed theory for the developm...
