Gamma knife: hydrocephalus as a complication of stereotactic radiosurgical treatment of an acoustic neuroma

Am J Otol. 1990 Sep;11(5):330-3.


Stereotactic radiosurgery is at present being marketed as a reliable alternative to conventional tumor removal in patients with acoustic neuromas. Hearing preservation is possible and treatment modality is presented as being very low. A case history is presented, in which a patient with an 18 mm tumor and normal hearing developed severe hydrocephalus and dizziness 9 months after irradiation, in addition to losing her hearing. Whether the Gamma knife is to be considered a reliable alternative to surgical removal of acoustic neuromas is discussed.
