Five years after the first inconspicuous MRI scan and 11 years after radiation therapy, a typical cavernoma with surrounding haemosiderin- and methaemoglobin-containing caverns, reflecting former haemorrhage, was detected in the FLAIR MRI sequence.

Subsequent MRI studies revealed a haemorrhagic transformed and space-occupying lesion diagnosed as a cavernoma (fig. 1, fig. 2).
In a cranial MRI performed in 2006, the FLAIR sequence revealed no pathological lesions anywhere in the brain. In particular, the right-sided supramarginal gyrus, where the cavernoma would later develop, shows no evidence of any signal alteration.

The MRI scan was entirely normal, without evidence of vascular lesions (fig. 3).
