Parathyroid Hormone and Subclinical Cerebrovascular Disease: The Atherosclerosis Risk in Communities Brain Magnetic Resonance Imaging Study
We examined the relationship between elevated PTH level and white matter hyperintensities (WMHs) and subclinical infarcts measured on brain magnetic resonance imaging (MRI).

A Novel Brainstem Hemorrhage Model by Autologous Blood Infusion in Rat: White Matter Injury, Magnetic Resonance Imaging, and Neurobehavioral Features
Primary brainstem hemorrhage (BSH) has the highest mortality and morbidity as a subtype of intracerebral hemorrhage. A major limitation of BSH research is the lack of a corresponding animal model. The purpose of this study was to establish a novel rat model of BSH and to characterize the resulting brain injury, especially focusing on white matter injury.

Characteristics of Cerebral Hemodynamics in Patients with Ischemic Leukoaraiosis and New Ultrasound Indices of Ischemic Leukoaraiosis
The diagnosis of ischemic leukoaraiosis (ILA) is based on head magnetic resonance imaging (MRI) and exclusion of other causes of white matter hyperintensities (WMHs). Recent studies have shown increased arterial stiffness and diminished carotid flow in ILA patients. So far, there are very little data on intracerebral hemodynamic parameters in ILA. Due to the specific structure of the intracranial arteries, our aim was to investigate intracerebral hemodynamic parameters in ILA patients and, possibly, to find a reliable ultrasound index of combined intra- and extracranial cerebral arteries.

Acute Convexity Subarachnoid Hemorrhage Related to Cerebral Amyloid Angiopathy: Clinicoradiological Features and Outcome
The specificities of acute convexity subarachnoid hemorrhage (cSAH) related to cerebral amyloid angiopathy (CAA) and its evolution are not well known. We aimed to describe the clinicoradiological pattern, the magnetic resonance imaging (MRI) evolution, and the risk of recurrent bleeding in such patients.

Cervical Posterior Spinal Artery Syndrome: A Case Report and Literature Review
We report a case of left upper cervical posterior spinal artery (PSA) syndrome caused by atherosclerosis of the left vertebral artery. A 70-year-old female experienced sudden dizziness and paralysis of the left upper and lower limbs. Diffusion-weighted magnetic resonance imaging (DWI) of the brain showed high signal intensity at the vermis and lower left hemisphere of the cerebellum, and magnetic resonance angiography showed that the entire left vertebral artery was thin. The patient was treated with an intravenous infusion of tissue plasminogen activator 2 hours after symptom onset and made a full recovery.

Moyamoya Vessel Pathology Imaged by Ultra–High-Field Magnetic Resonance Imaging at 7.0 T
Prompt diagnosis of vessel pathology and appropriate treatment of moyamoya vasculopathy (MMV) are essential to improve long-term prognosis. The aims of our study were to explore the diagnostic value of ultra–high-field (UHF) magnetic resonance imaging at 7.0 T in MMV patients and to compare the applicability of two different 7.0 T vessel imaging modalities to 3.0 T magnetic resonance angiography (MRA) and digital subtraction angiography (DSA).

Isolated Central Nervous System Vasculitis as a Manifestation of Neurosarcoidosis
A 62-year-old male presented to our clinic with recurrent fever, skin lesions (petechiae), scleral wounds, and hilar adenomegaly. A diagnosis of sarcoidosis was established, which resolved with corticosteroid treatment. After a few months, the patient developed confusion and behavioral changes, with few objective neurological deficits. Brain magnetic resonance imaging showed slight focal meningeal enhancement (prepontine region). The level of angiotensin-converting enzymes was normal in the serum and increased in the cerebrospinal fluid.

Subarachnoid Hemorrhage due to Spinal Cord Schwannoma Presenting Findings Mimicking Meningitis
We report an unusual case of spinal SAH mimicking meningitis with normal brain computed tomography (CT)/magnetic resonance imaging (MRI) and negative CT angiography. Cerebrospinal fluid examination results were consistent with the manifestation of SAH. Spinal MRI performed subsequently showed an intradural extramedullary mass. The patient received surgery and was finally diagnosed with spinal cord schwannoma.

Multiple Cerebral Infarctions in a Patient with Adenomyosis on Hormone Replacement Therapy: A Case Report
A 59-year-old woman was admitted to our hospital because of repeated episodes of bilateral hand weakness. She had a 10-year history of combined estrogen –progestin therapy for menopausal symptoms. Magnetic resonance imaging on admission showed multiple hyperintense lesions in bilateral cerebral and cerebellar cortices on diffusion-weighted imaging. Transesophageal echocardiography showed thrombus formation on the aortic valve and moderate aortic i nsufficiency. Laboratory test demonstrated elevated CA125 (334.8 U/mL) and D-dimer (7.0 µg/mL) levels.

Evolution of Subarachnoid Hemorrhage Extension in Lobar Hemorrhage in the Early Chronic Phase and the Impact on Cerebral Amyloid Angiopathy Criteria
Subarachnoid hemorrhage extension (SAHE) in acute lobar hemorrhage (LH) is frequent. Little is known about the short- and medium-term radiological evolution of SAHE. Our aim was to study this evolution by magnetic resonance imaging (MRI).

Relationship between the Carotid Plaque T1 Relaxation Time and the Plaque-to-Muscle Signal Intensity Ratio on Black-Blood Magnetic Resonance Imaging Scans
Black-blood magnetic resonance imaging (BB-MRI) is useful for the characterization and assessment of carotid artery plaques. The plaque-to-muscle signal intensity (SI) ratio (plaque/muscle ratio [PMR]) is used widely to evaluate plaques. However, the correlation between the PMR and the T1 relaxation time needs to be determined. We measured the T1 relaxation time of carotid plaques using T1 mapping and compared the results with the PMR on BB-MRI scans.

Recurrent Hemorrhagic Venous Infarctions Caused by Thrombosis of a Pontine Developmental Venous Anomaly and Protein S Mutation
A 34-year-old man presented with an acute onset of upbeat nystagmus, slurred speech, and limb and truncal ataxias. The patient had a history of limb ataxia and gait disturbance previously treated as brainstem encephalitis with corticosteroids 3 years previously. Brain magnetic resonance imaging showed pontine developmental venous anomaly (DVA) and hemorrhagic infarction within the drainage territory of the DVA. Three months later, the patient exhibited recurrent limb ataxia, double vision, and numbness of the left side of the body.

Thrombotic Thrombocytopenic Purpura with Concomitant Progressive Cerebral Microbleeds
We report a young patient with refractory TTP who has developed multiple multifocal cerebral microbleeds on his brain magnetic resonance imaging scans. TTP-associated thrombotic microangiopathy resulting in diffuse microthrombi formation in the microcirculation and hypoperfusion might be an underlying etiology.

Dermatomal Sensory Manifestations in Opalski Syndrome
A 31-year-old Japanese woman presented with sudden-onset unstable gait followed by nuchal pain. A neurological examination revealed right-sided limb weakness and decreased pain and thermal sensation on the left side below the level of the L1 dermatome. A lower lateral medullary infarction with ipsilateral hemiplegia, known as Opalski syndrome, caused by spontaneous vertebral artery dissection was diagnosed by magnetic resonance imaging. The spinothalamic tract in the medulla oblongata has a topographic arrangement of sensory fibers, and the dermatomal sensory deficit in this case can be explained in relation to that.
