Figure 2. Magnetic resonance imaging of brain in (A) T1-weighted images and (B) T2-weighted images in axial section showing a predominantly T1 isointense and heterogeneous T2 hyperintense mass. Post-contrast T1 images in the (C) axial and (D) sagittal view showing a solid and cystic nasal mass (green arrow) involving both temporal bones and extending intracranially with dura thickening and enhancement (white arrow block). This mass demonstrates a significant fluid restriction seen in (E) diffusion-weighted images and (F) apparent diffusion coefficient sequences.
