Female, 57 years old, with multiple sclerosis, assess for progression. Numerous foci of T2 hyperintensity are seen predominantly within the periventricular white matter and corpus callosum. These lesions are of similar size and distribution to that noted on the prior examination allowing for differences in technique. Small lesions are also seen within the right pons and left cerebellar hemisphere, unchanged. Also noted are areas of faint cortical T2 signal abnormality, most notably along the left central and precentral sulci, unchanged.The lesions noted above demonstrate varying degrees of T1 hypointensity ranging from barely detectable to markedly hypointense, appearing similar to prior. None of the above lesions demonstrates significant enhancement. No new lesions are detected.Brain parenchymal morphology is otherwise unremarkable. Brain volume is relatively preserved. No pathologic extra-axial collections are seen.Opacification or mucosal thickening is noted within the left sphenoid sinus.
No significant interval change is seen in the size, number or appearance of multiple white matter and cortical demyelinating lesions.
