Meningiomas – Single or More than 1 Fraction?
Meningiomas are typically benign intracranial tumours, more common in females than males. A common site of presentation involves the cavernous sinus, with cranial nerve deficits a relatively routine feature at diagnosis. Proximity to the optic nerve/chiasm is a determinant of how radiotherapy is delivered. The end point for benefit, as with most benign tumours, is lack of progression, achieved in typically greater than 90% of treated patients, irrespective of modality.
