 This limited surgical planning exam redemonstrates a T2 hyperintense 17 x 18 mm lesion within the left pars opercularis. There are a few scattered unchanged punctate foci of T2 hyperintensity throughout the supratentorial white matter that are most compatible with mild chronic small vessel ischemic disease.
Pretreatment MRI redemonstrates an unchanged lesion within the left pars opercularis likely representing low-grade glial neoplasm.
