Stable size of the homogeneously enhancing left cerebellopontine angle mass which displaces the adjacent pons and causes mild effacement of the fourth ventricle. This mass extends into and expands the left internal auditory meatus.
Codominant transverse sinuses communicate across the midline. This mass lies in direct contact with the left sigmoid sinus and intracranial internal jugular vein. No definite venous sinus invasion. No sinus compression or stenosis. No filling defect within either venous structure to suggest the presence of thrombosis.
