RADIATION NECROSIS AFTER CAVERNOMA RADIOSURGERY SIMULATING BRAIN HIGH-GRADE GLIOMA – A CASE REPORT AND REVIEW OF THE LITERATURE

We report a 62-year-old female patient who came to our institution due pain and limited movements in the neck area, nausea, headache. The magnetic resonance imaging (MRI) revealed single larger two smaller lesions with appearance of cavernomas left parietal brain region. was consulted neurosurgeon judged be inoperable.
