Axial (a, c, e) and coronal (b, d, f) enhanced T1 MR images reveal enhancing masses along the left frontoparietal-temporal region and the orbital region with dislocation of the optic nerve at onset (a, b) and in one-year (c, d) and two-year (e, f) follow-up, respectively.

Brain and orbit MRI revealed in left frontoparietal-temporal region extra-axial thickening of the dura mater with enhancement and perilesional oedema, infiltrating the sphenoorbital fissure, and an isointense mass with enhancement in the orbital region with dislocation of the optic nerve, which was thought to be consistent with a meningioma (Figures 1(a) and 1(b)). One year later, MRI showed slight reduction of the parietal-temporal lesion (Figures 1(c) and 1(d)), and levetiracetam therapy was stopped. The third brain MRI, performed approximately two years after diagnosis, showed a further reduction of the parietal-temporal lesion and of the left intra-orbital mass that enhanced uniformly after gadolinium administration (Figures 1(e) and 1(f)).
