Abstract

Case Report: The case of an unusual glioblastoma lacking contrast enhancement in computed tomography (CT) and conventional magnetic resonance imaging (MRI) is reported. The low uptake in positron emission tomography (PET) with F18-fluorodeoxyglucose (FDG) suggested a low-grade tumor or a benign inflammatory lesion. Only a significantly increased regional tumor blood volume identified by dynamic MRI (bolus tracking) and a markedly elevated choline level in magnetic resonance spectroscopy (MRS) suggested a highly malignant tumor, which was confirmed histologically (glioblastoma). The role of advanced functional imaging techniques in a typical gliomas lacking contrast enhancement is discussed.
