Summary

Ischaemic microangiopathic features have recently been incorporated into the criteria for cerebral amyloid angiopathy (CAA).

ApoE genotyping (presence of the E4 allele) is routinely used to help determine the aetiology of a haemorrhagic microangiopathy found on MRI.

Chronic ischaemic disease in CAA is characterised by the presence of :

* multispot pattern on the FLAIR sequence
* severe periventricular FLAIR hypersignals with posterior predominance

The main aim of this study was therefore to analyse the frequency of the presence of one (or two) E4 allele(s) on ApoE genotyping in patients with suspected CAA based on ischaemic MRI involvement with a typical radiological pattern.
