Osteoplastic trephination in the right occipitoparietal area with decompression trepanation of the posterior cranial fossa was performed. Fibroplastic meningioma of the cerebellum tentorium was removed (the second stage according to Simpson). It was followed by occlusion of giant aneurysm of the cavernous segment on the right ICA.
