Abstract: Objective: Diffusion-weighted imaging (DWI) is commonly detected after spontaneous intracerebral hemorrhage (sICH) and is associated with poor functional outcomes. However, the etiology and significance of DWI lesions remain unclear. Thus, our study aimed to explore the prevalence and risk factors of acute ischemic lesions in sICH and discussed the possible mechanisms.

Methods: We conducted a retrospective review of a consecutive cohort of 408 patients from June 2013 to October 2019 with sICH, who had brain computed tomography (CT) and magnetic resonance imaging (MRI) within 14 days of symptoms onset. Acute ischemic lesions were assessed on MRI using DWI lesions. We compared the clinical and imaging characteristics of patients with and without DWI lesions. The data were analyzed by univariate and multivariate logistic regression.

Results: Among the enrolled 408 patients, the mean age was 56.8 ± 14.5 years, 68 (16.7%) of them had been diagnosed with diabetes mellitus (DM). DWI lesions were observed in 89 (21.8%) patients, and most of them had a history of lacunar infarctions, which were located in cortical or subcortical. In multivariate logistic regression analysis, DM (odds ratio (OR) 3.962, p <0.001), severe deep white matter hypertensities (DWMH) (OR 2.463, p =0.001) and severe centrum semiovale enlarged perivascular spaces (CSO-EPVS) (OR 2.679, p =0.001) were independently associated with the presence of DWI lesions.

Conclusion: In our cohort, we found DM, severe DWMH and severe CSO-EPVS were the independent risk factors in sICH patients with DWI lesions.
