Acoustic neuromas are benign neoplasms that most often arise from the vestibular nerve. Many patients with this tumor experience some degree of vestibular symptoms. However, patients rarely complain of rotatory vertigo. Acoustic neuromas are known to exhibit a cystic appearance in some patients. It was hypothesized that cystic change might be a causative factor for rotatory vertigo. A retrospective study of 178 patients with unilateral acoustic neuroma who underwent surgery in the Department of Otolaryngology at Tokyo Medical and Dental University was carried out. The cystic appearance of the tumors was detected preoperatively by magnetic resonance imaging and confirmed at surgery. The relationship between cystic change of the tumor and presentation with rotatory vertigo was examined. Of the 178 patients studied, only 10 had both cystic change of the tumor and rotatory vertigo, and 120 had neither cystic tumor nor rotatory vertigo. Of the remaining 48 patients, 24 experienced rotatory vertigo with negative findings for cystic tumor and the other 24 had evidence of cystic tumor but no rotatory vertigo. Tumor with cystic change was observed in 34 patients, accounting for 19.1% of all patients studied. Rotatory vertigo was also experienced in 34 patients (19.1%). Of the 34 patients with cystic lesions, 29.4% (10) had rotatory vertigo. The difference in percentage of the two groups did not reach statistical significance. It is suggested that there may be other factors causing rotatory vertigo in patients with acoustic neuromas than cystic change of the tumor.
