Surveillance of CCM. There is interval decrease in size of the T1 and T2 hyperintense lesion in the inferior aspect of the right basal ganglia, now measuring up to 4 mm, previously 9 mm. There is persistent extensive surrounding susceptibility effect, which extends into the adjacent right optic tract. There is a small left frontal developmental venous anomaly. There is no evidence for new hemorrhage or recent infarct. There is no midline shift. The ventricles and sulci are unchanged in size and configuration. The orbits, skull, paranasal sinuses, and mastoid air cells are unremarkable.
