44-year-old female with left AA dx in 2011. S/p partial resection, RT/TMZ + TMZ. Now off all tx for years, per chart since 2011. There is no restricted diffusion to indicate ischemic infarction.Again seen is increased FLAIR/T2 signal intensity in the left posterior frontal and parietal lobe extending from the cortex to the left lateral ventricle appearing similar to prior study. There is persistent internal enhancement which overall appears decreased in extent from MRI study dated 6/13/2014 and currently measures 25 mm x 19 mm. There is some intrinsic T1 signal within the region of enhancement. There are some internal foci of low signal on susceptibility weighted imaging which appear more conspicuous compared to prior study on 10/10/2014 likely representing evolution of blood products.There are no new intraparenchymal lesion is identified. There are no new areas of abnormal enhancement or signal intensity. There is no intraparenchymal hemorrhage. There is mild expansion of the trigone of the left lateral ventricle similar to prior exam with no mass effect or midline shift.
Left posterior parietal and frontal lobe area of T2/FLAIR hyperintensity appears similar to prior study, however the extent of internal enhancement has decreased from study in 6/16/2014 and not significantly changed from the most recent MRI study on 2/11/2015.Note that the corrected relative cerebral blood volume sequence from perfusion imaging could not be generated. An addendum will be made to the report when this becomes available.
