Figure 2. Magnetic resonance imaging. (A) Magnetic resonance imaging in axial T1 section. The red arrow points to a solid extensive/ infiltrative lesion in the sphenoid body, on the right side of the midline, occupying a large part of the sphenoid sinus and causing bone erosions on the posterior, lateral, and superior walls. There was also extension to the right cavernous sinus, where it involved about 180° of the cavernous segment of the right internal carotid. (B) Magnetic resonance imaging coronal T2 section. The red arrow indicates a solid extensive/infiltrative lesion in the sphenoid body, on the right side of the midline, occupying a large part of the sphenoid sinus, causing bone erosions on the posterior, lateral, and superior walls. There was also extension to the right cavernous sinus, where it involved about 180° of the cavernous segment of the right internal carotid artery.
