Interval left parietal burr hole. There has been slight progression of the FLAIR hyperintensity within the left pre- and postcentral gyri, left middle frontal gyrus and posterior left superior frontal gyrus, with slightly increased mass effect. FLAIR hyperintensity within the medial left occipital lobe has also slightly progressed. Increased DWI signal on ADC measurement appears to be T2 shine through.
No enhancement within the regions of FLAIR abnormality. Smooth thin pachymeningeal enhancement is again demonstrated bilaterally. No brainstem abnormality demonstrated.
Periventricular and deep white matter foci of FLAIR hyperintensity are again demonstrated, consistent with moderate chronic small vessel ischemic change.
Conclusion: Mild progression of the FLAIR hyperintensity and mass effect within the left frontal, parietal and occipital lobes. No brainstem abnormality.
