Treatment plan for a cerebellopontine angle epidermoid tumor, the tumor was covered by 15 Gy at a 55% isodose line. One percent of the brainstem received 8 Gy, the pineal gland received 9 Gy

Treatment plan for a patient with an epidermoid tumor and associated trigeminal neuralgia. 80 Gy hotspot was placed on the nerve while modeling 12 Gy isodose around the tumor. The optic pathway received 1.5 Gy on 1% of its volume; brainstem received 9 Gy on 1% of its total volume, and the pineal gland received a total of 1.7 Gy

Treatment plan for a cerebellopontine angle epidermoid tumor causing trigeminal neuralgia. An 80 Gy hotspot was placed on the trigeminal nerve, and a 12 Gy isodose curve was modeled around the tumor. At risk structures including the brainstem received only 8 Gy at 7% of its total volume
