[The relationship between the clinical picture and course of acoustic nerve tumors and the direction of their growth in the cerebellopontine angle].

The data of clinical, surgical and post-mortem studies in 95 patients with neurinomas of the acoustic nerve permitted to eliminate 3 variants in the growth of neoplastical process into the ponto-cerebellar angle: 1) subtentorial (the upper variant) -- 27 cases; 2) the middle line of the brain stem (middle variant) -- 15 cases; 3) the lower parts of the angle (lower variant)--52 cases. Depending upon the direction of the growth into this space and upon the stage of the disease there were differences in the succession, frequency and expressiveness of focal and general brain symptoms. The development of the disease also differed.
