Figure 2

Initial MRI images: (a, c) axial and coronal T1WI, (b, e) axial and coronal T2WI, and (c, f) axial and coronal T1WI after gadolinium intravenous administration. The left nasal, ethmoidal, and sphenoidal lesion (grey arrows) can be seen with cavernous extension (solid white arrows), with low signal on T1WI and T2WI and homogeneous enhancement after contrast administration, with sinus obstruction and retention of secretions in ethmoid and sphenoid sinuses (dashed white arrows). MRI, magnetic resonance imaging; WI, weighted image.
