The purpose of this article is to highlight to radiosurgeons the potentially serious implications of this problem through illustrative case studies.<\/jats:p><\/jats:sec>Methods<\/jats:title>Our linac stereotactic radiosurgery (SRS<\/jats:styled-content>) technique has been previously described, with stereotactic headring fixation and treatment delivered via cones or micro\u2010multileaf collimators using multiple arcs or static beams.<\/jats:p><\/jats:sec>Results<\/jats:title>Between N<\/jats:styled-content>ovember 1993 and O<\/jats:styled-content>ctober 2014, we treated 132 patients referred with a clinical diagnosis of AN<\/jats:styled-content>, the vast majority with 12\u2009Gy marginal dose. Three of these (2.3%), evident either at the time of treatment (2) or subsequently (1), had features instead consistent with cochlear schwannoma, facial schwannoma and meningioma, respectively. Each warranted significant modification to standard AN<\/jats:styled-content> outlining and fields. The meningioma progressed due to geographic miss. One other patient with recurrent facial schwannoma (not yet needing SRS<\/jats:styled-content>) was also referred with an incorrect diagnosis of AN<\/jats:styled-content>.<\/jats:p><\/jats:sec>Conclusion<\/jats:title>When rare variants of common medical problems are not identified before referral, there is a risk that \u2018blinkering\u2019 can lead to misdiagnosis and suboptimal treatment. Radiosurgeons need to be particularly mindful of this issue with AN<\/jats:styled-content>, which can mimic several other tumours occurring in the CPA<\/jats:styled-content> region, albeit with different patterns of spread. Optimal imaging, high\u2010quality radiology reporting and neuroradiology input at the time of SRS<\/jats:styled-content> planning within the setting of a specialised multidisciplinary team are highly desirable.<\/jats:p><\/jats:sec>","DOI":"10.1111\/1754-9485.12328","type":"journal-article","created":{"date-parts":[[2015,6,4]],"date-time":"2015-06-04T10:00:07Z","timestamp":1433412007000},"page":"474-479","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["When is an acoustic neuroma not an acoustic neuroma?
