{{::q4207mripreop.jpg?400|}}

Regarding the last previous control, there are no significant variations, however, when comparing the evolution of the previous studies over the last 2 years, a constant progression is identified both in [[FLAIR]] and in the diffusion of [[periventricular]] predominance, especially at the right [[parietal]] level, with involvement of the [[splenium]] of the [[corpus callosum]] and in the right hemi[[protuberance]] in the last 2 studies, both in diffusion and in FLAIR, with a progressive increase in uptake, without clear images of [[mass effect]] at the current time. The lesion is highly suggestive of lymphoma.
