 There is redemonstration of a bubbly internal T2 bright lesion with a rim of hemosiderin staining along the right hypothalamus, measuring 18 x 17 mm in the axial view and approximately 16 mm in the craniocaudal view, not significantly changed since previous study.There is a right-sided developmental venous anomaly which drains to the right internal cerebral vein, unchanged since the previous study. Surrounding hyperemia in the basal ganglia persists. There is a new or larger susceptibility focus in the right basal ganglia adjacent to the DVA that could represent microhemorrhage.Minimal punctate nonspecific T2 hyperintensities in the right periventricular white matter are unchanged. No new intracranial lesions detected. No new edema or mass effect, or extra-axial fluid collection. Ventricular size is normal.
1. No significant interval change in the size or morphology of a right hypothalamic cavernous malformation. Likewise, there has been no change in the appearance of an associated large developmental venous anomaly. 2. A new or larger focus of susceptibility is seen adjacent to the DVA in the right basal ganglia which may represent microhemorrhage.
