Clinical question: History of follicular lymphoma are the brain status post 4 cycles of MTR in need of restaging. Signs and symptoms: As above. Pre-and post-enhanced brain MRI:Negative diffusion weighted series.Examination demonstrates a slight prominence of cortical sulci and the supratentorial ventricular system without interval change since prior MRI exam from Michigan state University dated 12 -- 10 -- 14. Nonspecific band of flair hyperintensity surrounding the periventricular white matter without enhancement or interval change since prior exam is noted. Signal intensity of brain parenchyma is otherwise unremarkable.Post-enhanced images demonstrate no detectable abnormal parenchymal, leptomeningeal or calvarial enhancement.Unremarkable images through the orbits and including axial fat sat post enhanced series.Paranasal sinuses, mastoid air cells and bilateral middle ear cavities demonstrate normal pneumatization signal pattern.
1.Negative diffusion weighted images.2.Mild prominence of supratentorial ventricular system for age with a surrounding nonspecific thin band of flair hyperintensity without enhancement. Finding could represent post treatment change.3.Unremarkable pre-and post enhanced brain MRI otherwise.4.Unremarkable calvarium, orbits, paranasal sinuses and mastoid air cells.5.No appreciable interval change since prior brain MRI exams from Michigan state University dated 12 -- 10 -- 14
