High-grade glioma: refined diagnostics steering stratified therapy.

An adequately sampled tumor histology that is evaluated by an experienced neuropathologist is the current international standard for the diagnosis of high-grade gliomas. We present the case of a 30-year-old female for whom clinical and radiological information dramatically changed the histological diagnosis. We suggest a new algorithm including these parameters to refine the accuracy of histological diagnosis both for standard treatment and centrally reviewed clinical trials.
