T2 hyperintensity (Figure 1) and T1 iso-signal compared to the gray matter located in the left pontine cistern, with a large, well-defined base at the level of the cerebral tentorium, approximately 1.5/1/1.5 cm (diam AP/LL/CC) (Figures 2 and 3), homogeneous, marked as a gadolinophil tumor, with a visible "dural tail", noninvasive, nondiffuse, with a slight mass effect on the pons, which indicate the presence of a meningioma. Mention should be made of the fact that the mass is directly connected to the cisternal portion of the trigeminal nerve, on its entrance to Meckel's cave. There were many well-defined, bilateral, periventricular, 6 mm, FLAIR, and T2 hyperintensity images, with no restriction in DWI/ADC, small microangiopathic ischemic demyelinated lesions.
