Objective We aim to test whether the presence of cortical superficial siderosis (cSS), a marker strongly associated with cerebral amyloid angiopathy (CAA), is likely to modify the underlying microangiopathy from hypertensive cerebral small vessel disease (HTN-cSVD) to CAA in patients with a combination of lobar and deep intracerebral hemorrhage (ICH)/cerebral microbleeds (CMBs) (mixed ICH/CMBs).

Background HTN-cSVD has been shown to be the predominant microangiopathy in patients with mixed ICH/CMBs.

Design/Methods

Brain MRIs from a prospective database of consecutive non-traumatic ICH patients admitted to a single referral center (2003 to 2019) were reviewed for the presence of CMBs, cSS, and non-hemorrhagic CAA markers (lobar lacunes, centrum semiovale enlarged perivascular spaces (CSO-EPVS), and multispot pattern of leukoaraiosis). The frequency of CAA markers and left ventricular hypertrophy (LVH), a marker for hypertensive end-organ damage, were compared between mixed ICH/CMB patients with cSS (mixed^+cSS) and without cSS (mixed^–cSS) in univariate and multivariate models.

Results

Of 1824 ICH patients, 40 had mixed^+cSSand 256 had mixed^–cSS. LVH was less common in patients with mixed^+cSS compared to those with mixed^–cSS (34% vs. 59%, p = 0.01). The frequency of multispot pattern (18% vs. 4%, p < 0.01) and severe CSO-EPVS (33% vs. 11%, p < 0.01) were higher in patients with mixed^+cSScompared to mixed^–cSS, whereas lobar lacune frequency was similar (23% vs. 20%, p = 0.67). In a logistic regression model, older age (aOR 1.04 per year, 95% CI [1.01–1.08], p = 0.01), presence of multispot pattern (aOR 5.82, 95% CI [1.82–18.60], p < 0.03), severe CSO-EPVS (aOR 4.08, 95% CI [1.73–9.61], p < 0.01), and LVH (aOR 0.43, 95% CI [0.20–0.94], p = 0.03) were independently associated with mixed^+cSS after further adjustment for sex and hypertension.

Conclusions

CAA-related markers are common among patients with mixed ICH/CMBs and cSS, suggesting that CAA may be the underlying microangiopathy in such patients.
