Atypical Meningioma: A Reported Case

Early studies of atypical meningiomas confirmed that total resection of meningiomas reduces recurrence compared with subtotal resection. These studies also provided the first evidence of the usefulness of radiotherapy as adjuvant treatment for subtotally resected atypical meningiomas. Radiotherapy of meningiomas is based on the principles of radiobiology, in particular the concept of biologically effective dose (BED) of radiation, the calculation of which makes it possible to compare different radiotherapy regimens. This case study aimed to demonstrate that radiation therapy is a real therapeutic alternative in the treatment of subtotally resected atypical meningiomas.
