Fig. 2.

MRI scans at one month post presentation. (A) Post contrast coronal T1 with fat saturation. The upper blue arrow demonstrates the enlarged ophthalmic nerve (V1) and the lower blue arrow shows the enlarged maxillary nerve (V2) as they exit the orbit. (B) Post contrast coronal T1 with fat saturation. The blue arrows point to bilateral Meckel's cave. The right Meckel's cave (large blue arrow) enhances with contrast and is larger than the left Meckel's cave, which is normal and does not enhance with contrast. (C) Axial T1W. The blue line represents the interzygomatic line and demonstrates the proptosis of the right eye. (D) Post contrast coronal T1 weighted images with fat saturation. The bottom five small arrows demonstrate the abnormally thickened and contrast enhancing mandibular nerve V3 as it exits through the foramen ovale. The top large blue arrow points to the two upper branches of the trigeminal nerve, V1 and V2.
