Gliomatosis cerebri (GC) is a rare diffusely infiltrating usually bilateral glial tumor involving at least 3 lobes. Its etiology is controversial and is classified as neoplasm of unknown histogenesis.The prognosis is generally poor, survival ranges from weeks to years. The imaging appearances of GC may be similar to more common diseases like  herpes encephalitis, but the clinical presentations differ. We will be using material from our Neuroradiology Section to illustrate imaging findings and its correlation with clinical and histological features.  The purpose of this exhibit is: To review general GC issues To show characteristic imaging findings at computed tomography (CT) and magnetic resonance (MR) and its correlation with microscopic pathology features To explain the utility of MR advanced techniques in the diagnosis and monitoring To illustrate differences between GC and its principal differential diagnosis using sample cases and diagnostic algorithms

Epidemiology, natural history and clinical presentation of GC Review of imaging findings CT features Traditional MR features Functional imaging findings (Diffusion, perfusion and spectroscopic imaging) Radiopathologic correlation Differential Diagnosis Sample cases and diagnostic algorithms
