OBJECTIVE: The first objective of this paper is to report the clinical symptoms of 77 @entity1 and the results of their neurologic, vestibular, and audiological evaluations done with magnetic resonance imaging, which confirmed @entity1645 . The second objective is to report how the results of a vestibular evaluation can help neurosurgeons decide on the need for surgical treatment. STUDY DESIGN: Retrospective chart review of 77 @entity1 seen between 1988 and 2000. SETTING: Tertiary care center. @entity1 : The clinical data of @entity1 under diagnoses of @entity1645 , which was filed in the vestibular laboratory computer, was analyzed. INTERVENTION: The cases included in this study were derived from a population of @entity1 who were evaluated for @entity1296 , @entity393 , and @entity392 in the Torok Vestibular Laboratory. MAIN OUTCOME MEASURE: Occurrence of central vestibular findings in the @entity1 with @entity1645 . RESULTS: In this group of 77 @entity1 , 10 had bilateral @entity1274 and 22 had unilateral @entity1274 of varying severities. Horizontal spontaneous nystagmus was noted in 27 @entity1 , vertical @entity346 in 3, and downbeat nystagmus in 4 others. Saccadic dysmetria was noted in 4 @entity1 , @entity346 was impaired in 3, and smooth-pursuit impairment was noted in 12 of the group. Positional nystagmus was noted in 9 @entity1 . The Torok monothermal caloric test showed normal responses in 19 @entity1 , hyperactive responses in 43, decruitment in 45, and rebound caloric nystagmus in 20. Surgical decompression of the @entity1645 was completed in 33 @entity1 . CONCLUSION: From this study it is clear that the results of the basic vestibular function-test battery reflect the functional deficit in the vestibulocerebellum that is presumed by its ectopic position. These tests results have given our neurosurgeons a stronger foundation on which to base surgical decisions for this disease.
