There are few reports in the literature on this particular issue, and some questions are still unanswered, particularly regarding the characteristics of positional nystagmus that may distinguish between a true benign paroxysmal vertigo and a positional nystagmus associated with the tumor. We present the videonystagmographic patterns of seven patients with acoustic tumor who had paroxysmal positional nystagmus and analyzed its features. A concomitant true benign paroxysmal positional vertigo may be present during the follow-up of a non-treated patient, as the paroxysmal positional vertigo may be the first symptom of the tumor, and it may show characteristics that are very similar to a posterior semicircular canal canalolithiasis or a horizontal canal \u201cheavy or light cupula\u201d. The possible mechanisms are discussed.<\/jats:p>","DOI":"10.3390\/audiolres13020026","type":"journal-article","created":{"date-parts":[[2023,4,14]],"date-time":"2023-04-14T02:28:12Z","timestamp":1681439292000},"page":"304-313","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Paroxysmal Positional Nystagmus in Acoustic Neuroma Patients"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5913-1484","authenticated-orcid":false,"given":"Francesco","family":"Comacchio","sequence":"first","affiliation":[{"name":"Otolaryngology Unit and Vertigo Regional Specialized Center, Sant\u2019Antonio Hospital, Via J.
