A jugular foramen schwannoma simulating an acoustic tumor with recovery of retrolabyrinthine cochleovestibular function.

Our literature review has tabulated 33 jugular foramen neuromas that appeared either as a neurologic "syndrome of the jugular foramen" like a glomas tumor, or similar to an acoustic tumor. The few posterior fossa tumors involving the eighth nerve or encroaching upon it that have been removed and resulted in cochleovestibular preservation or recovery have been reviewed. A rare case of jugular foramen schwannoma with cochleovestibular preservation after total removal has been extensively studied with preoperative and postoperative cochleovestibular tests.
