Abstract
INTRODUCTION Aneurysmal subarachnoid hemorrhage (aSAH) and intracerebral hemorrhage (ICH) are main forms of hemorrhagic stroke. Data regarding cerebral small vessel disease (SVD) burden and incidental small lesions on diffusion-weighted imaging (DWI) following aSAH are sparse. PATIENTS AND METHODS We retrospectively analyzed a prospective cohort of aSAH and ICH patients with brain MRI within 30 days after onset from March 2015 to January 2023. White matter hyperintensity (WMH), lacune, perivascular space, cerebral microbleed (CMB), total SVD score, and incidental DWI lesions were assessed and compared between aSAH and ICH. Clinical and radiological characteristics associated with small DWI lesions in aSAH were investigated. RESULTS We included 180 patients with aSAH (median age [IQR] 53 [47-61] years) and 299 with ICH (63 [53-73] years). DWI lesions were more common in aSAH than ICH (47.8% vs 14.4%, p < 0.001). Higher total SVD score was associated with ICH versus aSAH irrespective of hematoma location, whereas DWI lesions and strictly lobar CMBs were correlated with aSAH. Multivariable analysis showed that shorter time from onset to MRI, anterior circulation aneurysm rupture, CMB ⩾ 5, and total SVD score were associated with DWI lesions in aSAH. DISCUSSION AND CONCLUSION Incidental DWI lesions and strictly lobar CMBs were more frequent in aSAH versus ICH whereas ICH had higher SVD burden. Incidental DWI lesions in aSAH were associated with multiple clinical and imaging factors. Longitudinal studies to investigate the dynamic change and prognostic value of the covert hemorrhagic and ischemic lesions in aSAH seem justified.

Abstract
PURPOSE OF REVIEW Sporadic cerebral amyloid angiopathy (CAA) is a highly prevalent small vessel disease in ageing population with potential severe complications including lobar intracerebral hemorrhage (ICH), cognitive impairment, and dementia. Although diagnosis of CAA was made only with postmortem neuropathological examination a few decades ago, diagnosing CAA without pathological proof is now allowed in living patients. This review focuses on recently identified biomarkers of CAA and current diagnostic criteria. RECENT FINDINGS Over the past few years, clinicians and researchers have shown increased interest for CAA, and important advances have been made. Thanks to recent insights into mechanisms involved in CAA and advances in structural and functional neuroimaging, PET amyloid tracers, cerebrospinal fluid and plasma biomarkers analysis, a growing number of biomarkers of CAA have been identified. Imaging-based diagnostic criteria including emerging biomarkers have been recently developed or updated, enabling accurate and earlier diagnosis of CAA in living patients. SUMMARY Recent advances in neuroimaging allow diagnosing CAA in the absence of pathological examination. Current imaging-based criteria have high diagnostic performance in patients presenting with ICH, but is more limited in other clinical context such as cognitively impaired patients or asymptomatic individuals. Further research is still needed to improve diagnostic accuracy.

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.

Abstract
Intracerebral hemorrhage (ICH) is a common subtype of stroke and places a great burden on the family and society with a high mortality and disability rate and a poor prognosis. Many findings from imaging and pathologic studies have suggested that cerebral ischemic lesions visualized on diffusion-weighted imaging (DWI) in patients with ICH are not rare and are generally considered to be associated with poor outcome, increased risk of recurrent (ischemic and hemorrhagic) stroke, cognitive impairment, and death. In this review, we describe the changes in cerebral blood flow (CBF) and DWI lesions after ICH and discuss the risk factors and possible mechanisms related to the occurrence of DWI lesions, such as cerebral microangiopathy, cerebral atherosclerosis, aggressive early blood pressure lowering, hyperglycemia, and inflammatory response. We also point out that a better understanding of cerebral DWI lesions will be a key step toward potential therapeutic interventions to improve long-term recovery for patients with ICH.

Abstract
Background Previous meta-analysis had concluded that desferrioxamine mesylate (DFO) could effectively treat intracerebral hematoma (ICH) in animal models. We hope to confirm that DFO could treat ICH patients effectively through the systemic review and meta-analysis of clinical researches. Method Data extraction included hematoma volume (HV), reduction of National Institute of Health Stroke Scale (NIHSS) scores, and relative perihematomal edema (RPHE). The standard mean difference (SMD) and 95% confidence interval (95%CI) were calculated by fixed effects model. I-square (I2) statistic was used to test the heterogeneity. All p values were two-side with a significant level at 0.05. Results Five randomized controlled trials were included in the meta-analysis, which included 239 patients. At 7 days after onset, there was significant difference of RPHE development (− 1.87 (− 2.22, − 1.51) (I2 = 0, p = 0.639)) and significant difference of HV absorption (− 0.71 (− 1.06, 0.36) (I2 = 17.5%, p = 0.271)) between DFO and control groups. There was significant difference of reduction of NHISS scores (0.25 (0.05, 0.46) (I2 = 0, p = 0.992)) between DFO and control groups at 30 days after onset. Conclusion DFO reduced HV and perihematomal edema in ICH patients at 7 days after onset and improve neurological function at 30 days after onset efficiently and safely. DFO might be a new route of improving treatment of ICH.

Abstract
Objective This study aimed to compare effects of cerebral small‐vessel disease (cSVD) burden and cerebral artery stenosis (CAS) on acute ischemia in intracerebral hemorrhage (ICH) and their interaction with mean arterial pressure (MAP) change. Methods We recruited consecutive patients with acute primary ICH. Brain magnetic resonance imaging and angiography were performed to quantify diffusion‐weighted imaging (DWI) lesions, CAS, and cSVD markers, which were calculated for the total cSVD score. Multivariable regression models were adopted to explore their associations by DWI lesions size (<15 vs. ≥15 mm) and median MAP change stratification. Results Of 305 included patients (mean age 59.5 years, 67.9% males), 77 (25.2%) had DWI lesions (small, 79.2%; large, 20.8%) and 67 (22.0%) had moderate and severe CAS. In multivariable analysis, small DWI lesions were independently associated with higher total cSVD score (odds ratio [OR] 1.81, 95% confidence interval [CI] 1.36–2.41). and large DWI lesions were associated with more severe CAS (OR 2.51, 95% CI 1.17–5.38). This association was modified by MAP change (interaction p = 0.016), with stratified analysis showing an increased risk of large DWI lesions in severe CAS with greater MAP change (≥44 mmHg) (OR 3.48, 95% CI 1.13–10.74) but not with mild MAP change (<44 mmHg) (OR 1.21, 95% CI 0.20–7.34). Interpretation Total cSVD burden is associated with small DWI lesions, whereas the degree of CAS is associated with large DWI lesions, specifically with greater MAP change, suggesting that large‐artery atherosclerosis may be involved in ischemic brain injury, which is different from small‐vessel pathogenesis in ICH.

Abstract
BACKGROUND Small and remote acute ischemic lesions may occur in up to one-third of patients with spontaneous intracerebral hemorrhage (ICH). Possible mechanisms include cerebral embolism, small vessel disease, blood pressure variability and others. The embolic mechanism has not been adequately studied. Using transcranial Doppler (TCD), we assessed the incidence of spontaneous microembolic signals (MESs) in patients with acute ICH. METHODS Twenty acute ICH patients were prospectively evaluated within 48 h of hospital admission. Clinical and imaging data were collected. Continuous TCD monitoring was performed in both middle cerebral arteries for a one-hour period on days 1, 3 and 7 of hospital admission. Monitoring was performed in the emergency room, ICU or ward, according to patient location. We compared the frequency and risk factors for MES in patients with ICH and in 20 age- and gender-matched controls without history of ischemic or hemorrhagic stroke. RESULTS The mean age was 57.5 ± 14.1 years, and 60% were male. MESs were detected in 7 patients with ICH and in one control patient without ICH (35% vs 5%, p = 0.048). The frequency of MES on day 1 was 15% (3 of 20 patients), on day 3, 26% (5 of 19 patients) and on day 7, 37.5% (3 of 8 patients). Among patients with ICH, those with MES had a tendency to higher frequencies of dyslipidemia (83% vs 33%, p = 0.13) and lobar location of hemorrhages (71% vs 30%, p = 0.15). Two out of 6 patients with ICH who also underwent MRI had remote DWI lesions, of whom one showed MES on TCD. CONCLUSION Micro-embolic signals occur in over one-third of patients with ICH. Further research is needed to identify the sources of cerebral microembolism and their relationship with small acute infarcts in ICH.

Abstract
Background and Purpose: Whether patients with both lobar and deep cerebral microbleeds (mixed CMB) have advanced cerebral amyloid angiopathy (CAA), hypertensive angiopathy (HA) or both is uncertain. To get insight into the underlying small vessel disease (SVD) associated with mixed CMB, we explored its association with cortical superficial siderosis (cSS), a key marker of CAA and other MRI markers of SVD in patients with intracerebral hemorrhage (ICH). Methods: Of 425 consecutive patients with acute ICH who had received brain MRIs, 260 had ≥1 CMB and were included in the analysis. They were categorized as strictly lobar CMB (suggesting CAA), strictly deep CMB (suggesting HA) or mixed CMB. Clinical and imaging characteristics were compared (1) between the three CMB groups and (2) within mixed CMB patients according to the symptomatic ICH location. Results: Overall, 111 (26%) patients had mixed CMB. Compared to strictly lobar CMB (n = 111) and strictly deep CMB (n = 38), patients with mixed CMB had a more severe burden of lacune, white matter hyperintensities and CMB. cSS was observed in 24.3% of patients with mixed CMB compared to 44.1% in strictly lobar CMB and 10.5% in strictly deep CMB (p < 0.0001). Among patients with mixed CMB, 44 (39.6%) had a lobar symptomatic ICH and 67 (60.4%) had a non-lobar ICH. Patients with non-lobar ICH were more likely to have hypertension, whereas those with lobar ICH were more likely to have cSS and chronic lobar ICH and had higher ratio lobar CMB count/total CMB count. Conclusions: Mixed CMB is frequently encountered in patients with ICH and appears as a heterogeneous group, suggesting that both CAA and HA may be contributing to mixed CMB. Neuroimaging markers including ICH location, cSS, and CMB distribution may indicate the predominant underlying vasculopathy, with potential prognostic implications.

Abstract
A 47-year-old HIV-seronegative woman with autoimmune hemolytic anemia (AIHA) was treated with corticosteroids for 8 months. She developed central nervous system dysfunction and was diagnosed with cryptococcal meningitis (CM) after detecting cryptococcus neoformans in the cerebrospinal fluid. The patient's clinical symptoms were worsened and unusual MRI findings of white matter lesions were noticed even after adequate treatment, which were quite unusual compared with typical characteristics of CM. This led us to carry out further investigations. Similar cases have been reported previously in published literature. Combined with clinical symptoms and MRI findings, the most likely diagnosis was Cryptococcal Meningitis-Immune Reconstitution Inflammatory Syndrome. Unfortunately, the patient deteriorated and died of respiratory failure. Cryptococcal Meningitis-Immune Reconstitution Inflammatory Syndrome may have MRI changes during the early onset of the disease (bilateral basal ganglia). We propose that close monitoring of the condition, meticulous MRI follow-up and brain biopsies should be indicated in such cases for treating them actively, so as to avoid worsening of the patients' condition.

Abstract
Background and Purpose- Convexity subarachnoid hemorrhage (cSAH) is an increasingly recognized presentation of cerebral amyloid angiopathy (CAA), usually revealed by transient symptoms, but data on its outcome are limited. We compared the risk of future intracerebral hemorrhage (ICH), cSAH, and death in patients with CAA after cSAH and after lobar ICH. Methods- Consecutive patients with probable CAA, based on the Boston criteria, presenting with cSAH (CAA-cSAH) or lobar ICH (CAA-ICH) were included. We obtained baseline clinical and magnetic resonance imaging data and follow-up information. Univariable and multivariable analyses were used to compare incidence rate for symptomatic ICH, symptomatic cSAH, and late-death (beyond 30 days) between patients with CAA-cSAH and CAA-ICH. Results- Among 105 patients (mean age, 76.7±7.5 years) enrolled, 44 participants presented with CAA-cSAH and 61 with CAA-ICH. The median follow-up was 22.2 months (interquartile range, 12.6-34.4). The symptomatic ICH rate (per person-year) was 10.5% (95% CI, 5.6-19.4) in patients with CAA-cSAH compared with 8.5% (95% CI, 4.4-16.4) in those with CAA-ICH (adjusted hazard ratio, 1.05; 95% CI, 0.32-3.43). The annual incidence rates of symptomatic cSAH (9.9% versus 3.8%; adjusted hazard ratio, 1.77; 95% CI, 0.43-7.28) and death (9.5% versus 17.8%; adjusted hazard ratio, 0.56; 95% CI, 0.22-1.43) were not significantly different between patients with CAA-cSAH and those with CAA-ICH. Conclusions- Patients with CAA-related cSAH have a poor outcome, with similar high risk of future ICH and long-term mortality than CAA patients after lobar ICH. Our findings may have important prognostic implication and guide management of patients with cSAH in CAA.
