case_images: A computed tomography (CT) of the brain and orbits revealed an extra-axial mass of 3 cm maximum diameter located in the left cavernous sinus, occupying the ipsilateral Meckel's cave, with heterogeneous density and intensely enhanced after contrast administration (Figure 1A (Fig. 1)). After the administration of contrast, it enhances intensely but heterogeneously, with hypocaptive areas in its interior suggesting schwannoma of the V pair (Figure 1B (Fig. 1)).
