Abstract
The objective is to describe a case of hypofractioned skull base meningioma radiosurgery.Clinical case. For 5 years, female patient S., 55 years old, suffered from headaches. In 2012, magnetic resonance imaging of the brain showed petroclival meningioma on the left actively and homogenously accumulating the contrast agent. The patient refrained from any type of treatment. Control magnetic resonance imaging showed an increase in tumor size up to 24 × 45 × 27 mm; at the lateral margin it spread to the left temporal area, at the medial margin it grew around the left optic nerve, chiasm spreading into the left maxillary sinus. We performed three-fraction radiosurgery for skull base meningioma according to hypofractionation scheme (7 Gr / fraction with 2 day interval). 37 months postoperatively, tumor volume had complete regression. There are no optic disturbances.Conclusion. This case report demonstrates treatment results of difficult structure tumor and describe radiosurgical possibilities in big size meningiomas.
