Computed Tomography and Magnetic Resonance Imaging Findings in Early Glioblastoma (e-GBM): Spotting the Wolf in Sheep’s Clothing

e-GBM should be considered in patients presenting with neurological symptoms, in particular seizures, when T2WI or FLAIR signal abnormalities in a cortical or subcortical location are seen with associated restricted diffusion. Hyperdensity on non-contrast CT imaging congruent with areas of signal change on MRI should also prompt clinicians to consider e-GBM as a differential diagnosis.
