Illustrative case: a 39-year-old female patient underwent MRI for intermittent tinnitus in January 2013 with diagnosis of an incidental convexity meningioma in the posterior fossa. Initially she refused any treatment. A follow-up MRI after 12 months demonstrated tumor progression with 4 mm growth in diameter. She refused microsurgical resection due to religious reasons (Jehovah's Witness) and underwent Cyberknife radiosurgery in April 2014 (single fraction SRS, 13 Gy, 70% isodose level). Throughout her further course until last follow-up in April 2020 she had no subjective complains nor neurological deficits. The annual follow-up MRIs showed stable disease with no reaction of the surrounding tissue. The red line represents the outlined tumour surface, the yellow line the applied 13 Gy surface dose, and the violet and blue lines the 9 Gy and 5 Gy isodose
