 There has been overall interval decrease in size of the numerous supratentorial and infratentorial metastatic lesions and associated vasogenic edema. For example, a lesion in the anterior left temporal lobe now measures up to 6 mm, previously 12 mm, and a lesion in the superior vermis measures up to 4 mm, previously 8 mm. There is diffuse subcortical and periventricular deep white matter T2 hyperintensity, which has slightly progressed. The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There is no midline shift. There is no evidence for intracranial hemorrhage or acute cerebral, brainstem, or cerebellar infarction. The skull and orbits are unremarkable.
1.Interval decrease in size of the numerous supratentorial and infratentorial metastatic lesions and associated vasogenic edema.2.Diffuse subcortical and periventricular deep white matter abnormality has slightly progressed. This is nonspecific and may be related to whole brain radiation superimposed on small vessel chronic ischemic changes.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
