Clinical question: GBM, cerebellar lesion growth? Signs and symptoms: MS. Pre and post enhanced brain MRI:A focus of FLAIR/T2 hyperintensity along the right lateral aspect of the fourth ventricle without enhancement is again noted and without convincing evidence of interval change.There is mild interval decreased size and mass effect of the focus of FLAIR hyperintensity involving the right anterior cingulate gyrus and surrounding the right frontal horn of lateral ventricle without enhancement.There is a visualization of a focus of enhancement within the right frontal horn of lateral ventricle and the ependymal lining with interval decreased size. The finding on current exam on FLAIR T2 weighted series measures at 18 x 11 compared to prior study the measurements of approximately 15 x 18 mm.Examination also demonstrate interval decreased size of a mildly enhancing mass along the dorsal aspect of right frontal surgical cavity since prior study. Prior exam the finding measured approximately 27 mm in AP axis compared to current study measurements of 18. This finding on coronal T2-weighted images measured approximately 32 mm in transverse axis compared to current study measurements of approximately 24 mm.Stable focus of FLAIR and T2 hyperintensity involving the cortex and subcortical white matter of left frontal lobe along its anterior superior aspect without enhancement and likely representing posttreatment changes.Ex vacuo dilatation of right lateral ventricle and mildly prominent left lateral ventricle with maintained midline remains similar to prior exam.
1.Interval decreased size of an enhancing mass within the right frontal horn and with involvement of the right frontal ependymal lining as detailed/measured above.2.Interval decreased size of an enhancing mass along the posterior edge of right frontal resection cavity as detailed/measured above.3.Interval mild decreased extent and mass effect surrounding the right frontal horn and right frontal cingulate generous without convincing evidence of enhancement.4.Stable focus of FLAIR hyperintensity along the interhemispheric aspect of the left frontal lobe without enhancement and likely representing posttreatment change.5.Stable focus of FLAIR hyperintensity along the right lateral aspect of fourth ventricle without enhancement.
