From: Sphenoid sinus aspergilloma clinically mimicking as malignancy—a case report
a T1-weighted axial MRI image shows hyper intense lesion filling the sphenoid sinus extending into adjacent greater wing of sphenoid bone, posterior ethmoid air cells, and clivus (blue arrow). The lesion appears hypo intense/dark on axial T2-weighted image (b) and sagittal T2-weighted image (c) confirming the proteinaceous content within the sinus. There is extension of lesion into bilateral cavernous sinus with partial encasement of bilateral cavernous segment of internal carotid arteries (red arrows). Sella is not seen completely separate from the lesion (c).
