This 51 year old male patient has a right hemiparesis and progressive brainstem dysfunction. The temporal lesion is probably a low grade tumor, but what about the brain stem lesion??? Could it be a paraneoplastic encephalitis or a brainstem gliomatosis? Any other suggestions?
Strange Lesion
and of course CE a well is lacking…
What about SWI? diffusion? perfusion? MRS? T1-CE? I think the whole set could be useful. Interesting is that lesions in the pons are on one half only. Did you consider performing biopsy on the temporal superficial lesion?
