Non-acoustic neuroma tumor (NANT) of the cerebello-pontine angle: a 15-year experience

Abstract

Between 1980 and 1994, 145 patients affected by tumors of the CP angle underwent surgery at the Division of Neurosurgery of the San Camillo Hospital in Rome. The 56 (39%) "non-acoustic tumors" have been analyzed with regard to epidemiologic factors, clinical picture, neuroimaging findings in order to determine their distinctive diagnostic features. Moreover, the surgical outcome and follow-up results are presented and compared with those of the literature.
