In , Harvey Cushing described the “cerebellopontine angle syndrome” as the constellation of progressive neurologic findings associated with lesions of this region, consisting of ipsilateral hearing loss followed by onset of facial hypesthesia, hydrocephalus, and brainstem compression leading to death. 3 Sir Charles Ballance is frequently credited with the first successful resection of a CPA tumor, .
