Magnetic Resonance Imaging Markers of Cerebral Small Vessel Disease in Hematoma Expansion of Intracerebral Hemorrhage
Hematoma expansion is an independent risk factor of unfavorable outcome after intracerebral hemorrhage (ICH), which always occurs in the early phase after symptoms onset. The relationship between underlying small vessel disease (SVD) and hematoma expansion was inconsistent in patients with ICH. We aimed to investigate the relationship between magnetic resonance (MR) characteristics of SVD and hematoma expansion in patients with ICH within 72 hours after symptoms onset.

Spinal Dural Arteriovenous Fistula Assumed to be Symptomatic after Placement of Lumbar Cerebrospinal Fluid Drain
A 69-year-old man presented with severe headache. Cranial computed tomography revealed diffuse subarachnoid hemorrhage. An anterior communicating artery aneurysm was identified and successfully obliterated by open microsurgery on the same day. Following placement of a continuous lumbar cerebrospinal fluid drain on hospitalization day 7, the patient developed a severe paraplegia and sensory loss below T6. Cerebral magnetic resonance imaging did not identify a responsible lesion. Spinal magnetic resonance imaging, however, showed extensive intramedullary hyperintensity on T2-weighted sequences.

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.

High-Resolution Magnetic Resonance Imaging Confirmed Atherosclerosis of an Intracranial Penetrating Artery: A Case Report
Intracranial branch atheromatous disease is an atheromatous pathophysiological process associated with occlusion or stenosis at the orifice of a deep penetrating artery. However, apart from autopsy, atherosclerosis in the penetrating artery has not been confirmed in vivo. In this case, we confirmed that the ostium was located in the parent artery plaque and demonstrated the atherosclerosis of the proximal penetrating artery by using high-resolution magnetic resonance imaging. HR-MRI can be used to identify the pathological changes in penetrating arteries and provides more reliable basic information for the clinical subclas...

Multiple Thrombi in the Heart in Trousseau Syndrome Caused by Pancreatic Carcinoma
A 65-year-old woman presented to our emergency room because of sudden onset of right hemiparesis with severe fatigue. Neurological examination revealed right hemiparesis with right facial numbness and an extensor planter response on the right side.Magnetic resonance imaging with diffusion-weighted imaging revealed multiple highintensity areas in both cerebral hemispheres and the right cerebellum. A diagnosis of acute stage of multiple brain infarctions caused by emboli was made. An abdominal computed tomography showed a pancreatic tumor with multiple liver metastases.

Disseminated Microinfarctions with Cerebral Microbleeds
Disseminated microinfarctions are uncommonly encountered in clinical practice. Here we describe a patient with long-standing cerebral microbleeds who developed acute cognitive decline in the setting of acute hypotension. Magnetic resonance imaging showed acute disseminated microinfarctions, with no change in microbleeds. This case emphasizes the important relationship between ischemic and hemorrhagic microvascular disease of the brain, especially in the setting of acute blood pressure changes compounding preexisting microvascular injury.

Arterial Spin Labeling Cerebral Perfusion Magnetic Resonance Imaging in Migraine Aura: An Observational Study
Changes in cerebral perfusion during migraine with aura (MA) have been assessed mainly using dynamic susceptibility contrast (DSC) magnetic resonance perfusion imaging. A contrast agent-free method to assess these changes would be desirable. We assessed changes in cerebral perfusion during MA using arterial spin labeling (ASL) perfusion magnetic resonance imaging.

Acute Intracranial and Spinal Subdural Hematoma Associated with Vardenafil
A 28-year-old healthy man was admitted to our hospital because of right-sided headache, vomiting, and lower back pain after the administration of vardenafil. Computed tomography and magnetic resonance imaging of the brain showed a small, right-sided, subdural hematoma. A lumbar magnetic resonance imaging showed a longitudinally extended subdural hematoma. He had no history of trauma. We speculated that vardenafil might have had an association with the bleeding. Several reports have suggested a relationship between phosphodiesterase-5 inhibitors and intracerebral or subarachnoid hemorrhage.

Neovascularization in Vertebral Artery Atheroma —A Dynamic Contrast-Enhanced Magnetic Resonance Imaging-Based Comparative Study in Patients with Symptomatic and Asymptomatic Carotid Artery Disease
This study aimed to explore the systemic nature of atherosclerosis by assessing difference in severity of neovascularization as quantified by DCE-MRI of vertebral arteries (VAs) between patients with symptomatic and asymptomatic carotid artery disease.

Conjugate Eye Deviation Caused by Upper Medial Medullary Infarction: A Case Report
Conjugate eye deviation (CED) is defined as a sustained shift in horizontal gaze toward 1 side, together with gaze failure to the other side, caused by lesions in the brainstem, basal ganglia, or cortical frontal eye fields. To date, very few reports have described CED in patients with medullary infarction. A 76-year-old woman presented with sudden onset of vertigo and right hemiparesis, accompanied by CED to the right with gaze palsy to the left. Her brain magnetic resonance imaging showed left upper medial medullary infarction involving the left nucleus prepositus hypoglossi (NPH) and adjacent to the left inferior olivary nucleus (ION).

Comparison of Premortem Magnetic Resonance Imaging and Postmortem Autopsy Findings of a Cortical Microinfarct
An 85-year-old woman diagnosed with amyotrophic lateral sclerosis died of pneumonia and was autopsied. Magnetic resonance imaging (MRI) performed 16days before death revealed an intracortical high-intensity lesion in her right temporal cortex on three-dimensional (3D)-double inversion recovery (DIR) and 3D-fluid-attenuated inversion recovery (FLAIR) images. Histopathological examination indicated a cortical microinfarct (CMI) juxtaposed to cerebral amyloid angiopathy. Recently, in vivo detection of CMIs using 3D-DIR and 3D-FLAIR on 3-tesla MRI has been reported, and postmortem MRI study confirmed the presence of CMIs.

A Chinese CARASIL Patient Caused by Novel Compound Heterozygous Mutations in HTRA1
Our objective is to reported a Chinese CARASIL patient caused by novel compound heterozygous mutations in HTRA1. Detailed clinical and neuroimaging examination were conducted in proband and her available family members. Sanger sequencing of NOTCH3 and HTRA1 was used to investigate causative mutations. The patient was born in an outbred family. She experienced recurrent transient ischemic attacks, hair loss, and low back pain. Brain magnetic resonance imaging showed multiple lacunar infarctions, diffuse leukoencephalopathy, and multiple microbleeds of white matter.
