Polyvascular disease: right frontal lobar haemorrhage due to cerebral amyloid angiopathy (A) in an 82-year-old man with a prosthetic aortic valve and extensive calcifications of the aortic arch and along the descending thoracic aorta (B). Three-dimensional digital subtraction angiography reconstructions of the same patient (C,D) show diffuse arterial dysplasia with ecstatic origin of an inferior temporal branch (arrow), a dysmorphic aneurysm of the Sylvian bifurcation of the middle cerebral artery (arrowhead), and an infra-millimetric aneurysm of the anterior communicating artery (*).
