Abstract
World Health Organization (WHO) grade III anaplastic meningioma is scarce. In this way, most studies compared WHO grade I and II. Otherwise, some authors are uncertain about using 18 F-FDG as a diagnostic tool to estimate the WHO grade, especially high. We report the case from a man with a grading tumor evolution from WHO grade II atypical to grade III anaplastic metastatic meningioma. This turning point was imaged using 68 Ga-DOTATOC and 18 F-FDG. Diagnostic was confirmed by histology. The case underlines the unparalleled power of molecular imaging characterized by high sensitivity staging and spectacular avidity changing relationship with grading tumor evolution.
