Multiple cavernous malformations in a 32-year-old man investigated for intraparenchymal haemorrhage. The patient turned out to be affected by familial cavernous angiomatosis. a T2-weighted image demonstrates a left frontal cavernous malformation surrounded by a thick ring of haemosiderin. b GE T2*-weighted image shows multiple punctate hypointense foci located in both hemispheres, corresponding to small cavernous malformations (arrows). c SWI minIP: there are supplemental cavernous malformations that are not detected by GE sequences (arrows). d SWI minIP, reformatted sagittal section: multiple small cavernous malformations located in the brainstem (arrows)
