Cerebellar pontine angle meningioma

Aponencephalic horn meningiomas include those whose tumors originate behind the petrous bone or invade the cerebellum, but do not include meningiomas originating from the slope. The first case of pontine cerebellar meningioma dates back to 1855. Cushing reported six cases from 1928 to 1938. However, the results were not satisfactory, and the average survival time was 12 months. The pontine cerebellar horn meningiomas are difficult to treat because there are many important neurovascular entanglements, so the postoperative results are poor. In recent years, with the development of microsurgery and the clinical application of CT and MRI, great progress has been made in the treatment of this disease. In 1980, Yasargil reported that 30 cases of apontine cerebellar meningioma were successfully removed. Meningiomas of the cerebellopontine angle mentioned here include those whose tumors originate behind the petrous bone or invade the cerebellum, but do not include meningiomas originating from the slope.
