Both were treated in a single plan to 50.4 Gy fractionated, like I usually would for an optic nerve sheath meningioma. By treatment end, the patient had a ...

Assuming the patient is a candidate for SRS, can consider delivering, in 5 fractions, 30 Gy as feasible to GTV, while underdosing PTV margin to a dose of 25 Gy while keeping optics structures within appr...
