Brain imaging of patient 6. Axial plane MR images show a large heterogeneous right temporal tumor, with mass effect and midline shift. The tumor displays hypointensity on the T1-weighted image (A), hyperintensity on the T2-weighted image (C), and weak enhancement after contrast media injection (B). An intratumoral vessel is seen (B). Diffusion signal is high (D) with low ADC. Diffusion is also restricted in the right occipital lobe (D) because of an ischemic injury caused by compression of the posterior cerebral artery.
