Lipopolysaccharide Induces Subacute Cerebral Microhemorrhages with Involvement of Nitric Oxide Synthase in Rats
Cerebral microhemorrhage (CMH) is a neuropathological term that could be easily found in cerebral amyloid angiopathy, intracerebral hemorrhages, etc. CMHs could be detected clearly in vivo by magnetic resonance imaging (MRI) –susceptibility-weighted imaging or MRI T2* scan. This terminology is now accepted in the area of neuroimaging. CMHs are quite common in elderly patients and are associated with several other neuropsychiatric disorders. The causes of CMHs are complicated, and neuroinflammation is considered as one of the well-accepted mechanical factors.

Bilateral Caudate Nucleus Infarctions Following Upper Gastrointestinal Bleeding
A 75-year-old woman presented with consciousness disturbance accompanied by hematemesis. Brain imaging revealed ischemia in the bilateral caudate nuclei and right cerebral watershed area due to stenosis of the right anterior cerebral artery (ACA) and bilateral internal carotid arteries (ICA), and hypoperfusion in the right caudate nucleus. The patient's only symptom was abulia, which gradually resolved. Further brain scans showed that the ICA stenosis had improved, although the right ACA stenosis persisted.

Inflammation Coupling Between Unstable Carotid Plaque and Spleen —A 18F-Fluorodeoxyglucos Positron Emission Tomography Study
This study was aimed to assess the hypothesis that unstable plaque formation in the carotid artery is one of phenotypes of chronic and systemic inflammation.

Unraveling Specific Brain Microstructural Damage in Moyamoya Disease Using Diffusion Magnetic Resonance Imaging and Positron Emission Tomography
Chronic ischemia may induce brain microstructural damage and lead to neurocognitive dysfunction in patients with Moyamoya disease (MMD). We applied neurite orientation dispersion and density imaging (NODDI) and 15O-gas positron emission tomography (PET) to elucidate the specific ischemic brain microstructural damage of MMD in the cortex and the white matter.

Authors ’ Response to “Barometric Pressure in Cerebral Amyloid Angiopathy: A Pressure to Bleed?”
The authors thank Dr. Vilanilam et al ’ comments to our recent article entitled “The Influence of Weather on the Incidence of Primary Spontaneous Intracerebral Hemorrhage (sICH)”. A study exclusively examining the influence of weather on patients with possible/probable cerebral amyloid angiopathy (CAA) may be helpful, although one would have to assume that elevations in blood pressure play no role in causing sICH in these patients. Furthermore, establishing a priori knowledge of normotension and CAA pathology would be difficult, and would require a large study population with serial blood pressure monitoring and MRI ...

Blood Type O Predicts Hematoma Expansion in Patients With Intracerebral Hemorrhage
Background: Hematoma expansion after acute spontaneous intracerebral hemorrhage (ICH) is well established to result in poor prognosis. Recent studies have demonstrated that the ABO blood type system has potential implications on hemostatic properties. The purpose of this study was to explore the potential association of blood type O with hematoma expansion in patients with ICH and validate the usefulness in predicting early hematoma expansion. Methods: We retrospectively enrolled consecutive patients with ICH who underwent baseline computed tomographic (CT) scan within 6 hours after onset of symptoms.

Dural Sinus Thrombosis with Nonsymptomatic Persistent Falcine Sinus: A Case Report
A 24-year-old woman was admitted to our hospital after convulsive status epilepticus. A cerebral magnetic resonance venography revealed a persistent fetal falcine sinus. Additionally, the posterior third of the superior sagittal sinus was hypoplastic and the abnormal deep venous drainage was accompanied. These abnormalities had already been detected by magnetic resonance imaging several years ago. In the present scan, we discovered a sinus thrombosis in the hypoplastic superior sagittal sinus. In the cerebral angiography, we observed delayed venous return in the left parieto-occipital lobe and hypothesized that cerebral ve...

Novel Approaches to Detection of Cerebral Microbleeds: Single Deep Learning Model to Achieve a Balanced Performance
Cerebral microbleeds (CMBs) are considered essential indicators for the diagnosis of cerebrovascular disease and cognitive disorders. Traditionally, CMBs are manually interpreted based on criteria including the shape, diameter, and signal characteristics after an MR examination, such as susceptibility-weighted imaging or gradient echo imaging (GRE). In this paper, an efficient method for CMB detection in GRE scans is presented.

Infratentorial developmental venous anomaly concurrent with a cavernoma and dural arteriovenous fistula
A 32-year-old woman underwent a head computed tomography scan after a traffic accident. A calcification in the left cerebellar hemisphere was disclosed. She did not complain of any symptoms, but neurological examination revealed cerebellar ataxia. She did not have any preceding episodes since birth, such as acute-onset headache. Magnetic resonance imaging showed past hemorrhage of the calcification lesion suggestive of a cerebellar cavernoma. A dilated vascular structure was also observed (Fig.  1A, B).

An unusual neurological presentation in a patient with primary hypereosinophilic syndrome
Hypereosinophilic syndromes are characterized by an increased number of blood eosinophils (usually more than 1.5  × 109) infiltrating tissues and causing organ damage through over-production of pro-inflammatory cytokines with heterogeneous clinical presentation. Here we present a case of a 47 years old male, with an unremarkable previous medical history, with a sudden onset of subungual hemorrhage and low b ack pain. Admitted for right arm weakness and vomiting, was raised the suspicion of acute cerebrovascular syndrome, but a brain CT scan with angiogram and perfusion sequences did not show any signs of early ischaemic...
