Enlarged perivascular spaces and small diffusion-weighted lesions in intracerebral hemorrhage.

ABSTRACT:

Objective

To examine the association between enlarged perivascular spaces (EPVS) and the prevalence and extent of small acute diffusion-weighted imaging (DWI) lesions (SA-DWIL) in patients with spontaneous supratentorial intracerebral hemorrhage (ICH).

Methods

We conducted a retrospective review of a consecutive cohort of 201 patients with spontaneous supratentorial ICH who had brain MRI with DWI within 1 month of ICH onset. We compared the clinical and imaging characteristics, including EPVS, of patients with and without SA-DWIL. We used univariate and multivariate logistic regression analyses to determine the variables associated with SA-DWIL.

Results

Small acute DWI lesions were detected in 27.9% (n = 56) of patients. Intraventricular and subarachnoid extension of
