MRI showed the typical lesion in the left posterior parietal operculum and insular cortex, facing Heschl's gyrus. At the medial border of the cavernoma, a small T1-hyperintense rim could be seen, that hadn't been there on a previous examination. Perifocal oedema on T2 was also a new finding, suggesting recent haemorrhage.
