A. V. Agapov. To the casuistry of tumors of the cerebellar-pontine angle. Journal of Neur. and psycho. named after S. S. Korsakov. Book 3 - 4. 1908

The author describes a case where, on the basis of clinical data - dizziness, coordination disorders, a long course and the absence of indications of lues during the life of the patient, it was suggested that the cerebellum was affected. An autopsy revealed the presence of two tumors, cystic degenerate, each about ¹/₂ of a chicken egg, located in the tonsilla et flocculus region of both hemispheres of the cerebellum, on the sides of the medulla oblongata (in the angle between the pons and the cerebellum). On cuts, it was found that the substance of the cerebellum was separated from the mass of the tumor and was only squeezed by the tumor, which was in connection with the auditory nerve under the pia mater.
