Recurrent Ischemic Stroke in a Patient with the Trousseau Syndrome Treated with Dabigatran
A 70-year-old man with multiple ischemic strokes was diagnosed with cardiac embolism and treated with dabigatran. Three months later, he suddenly developed vertigo and vomiting. Magnetic resonance imaging, showed recurrent lesions and blood tests revealed hypercoagulability, hypoproteinemia, and elevated cytokeratin 19 fragments that serve as a tumor marker of lung cancer. Chest computed tomography showed there were small nodules in bilateral lungs and swollen mediastinal lymph nodes. A conclusive diagnosis was impossible because the patient declined invasive procedures. We suspected primary lung cancer and diagnosed conco...

Spontaneous Isolated Posterior Inferior Cerebellar Artery Dissection: Rare but Underdiagnosed Cause of Ischemic Stroke
Conclusions: Clinical manifestations in ischemic type of spontaneous isolated PICAD were similar to those of intracranial vertebral artery dissection. Clinical course was relatively stable and benign. SWI was more helpful to suspect abnormality of posterior inferior cerebellar artery than conventional MRI or magnetic resonance angiography in our small series. Cerebral angiography is recommended in patients with clinically suspected spontaneous isolated PICAD for definite diagnosis.

Can Early Effective Anticoagulation Prevent New Lesions on Magnetic Resonance Imaging in Acute Cardioembolic Stroke?
Background: The timing of warfarin administration for acute ischemic stroke (AIS) patients with atrial fibrillation (Af) has not been established. We hypothesized that achieving targeted prothrombin time and international normalized ratio (PT-INR) at 2 weeks could prevent AIS patients with Af from developing a new lesion on diffusion-weighted magnetic resonance imaging (DW-MRI).Methods: Of consecutively enrolled AIS patients with Af between 2008 and 2011, we selected the patients who were given warfarin within 2 weeks of admission and had DW-MRI and blood test for PT-INR both on admission and at 2 weeks. Warfarin was st...

Fatal Intracranial Hemorrhage after Intravenous Thrombolytic Therapy for Acute Ischemic Stroke Associated with Cancer-related Nonbacterial Thrombotic Endocarditis
Nonbacterial thrombotic endocarditis (NBTE) is associated with hypercoagulability in patients with inflammatory states such as cancer and autoimmune diseases. Cardiac vegetations caused by NBTE often lead to life-threatening systemic thromboembolism that most frequently affects the brain, spleen, and kidneys. A 54-year-old woman diagnosed with ovarian cancer suddenly developed back pain and left hemiparesis. Although intravenous alteplase (rt-PA) therapy was administered to treat hyperacute ischemic infarction detected by magnetic resonance imaging, intracranial hemorrhage occurred in the left hemisphere several hours late...

Magnetic Resonance Imaging in Acute Ischemic Stroke Patients with Mild Symptoms: An Opportunity to Standardize Intravenous Thrombolysis
Patients presenting with mild stroke symptoms are excluded inconsistently from intravenous (IV) thrombolysis. We aimed to compare acute magnetic resonance imaging findings in patients with mild symptoms to those with more severe deficits to identify clinically mild patients who might benefit from IV thrombolysis.

Auditory Spatial Deficits in the Early Stage of Ischemic Cerebral Stroke
Clinical research, together with computed tomography/magnetic resonance imaging findings, proves that ischemic stroke (IS) that damages auditory pathways can cause hearing loss and impairment of higher auditory processes such as sound localization. The goal of the study was to find possible correlations between the IS risk factors, ischemic lesion volume and localization, neurologic status, and the sound localization capability in acute IS patients.

Implementation of a Community-Based Triage for Patients with Suspected Transient Ischemic Attack or Minor Stroke Study: A Prospective Multicenter Observational Study
Japan has the highest number of magnetic resonance imaging units in the world, and citizens can freely choose medical care at any hospital or clinic. We aimed to investigate the triage of patients with suspected transient ischemic attack (TIA) or minor stroke in this unique Japanese healthcare system.

Stroke Presentation of Acute Type A Aortic Dissection with 100% Perfusion-Weighted Imaging–Diffusion-Weighted Imaging Mismatch: A Call for Urgent Action
Acute stroke in the setting of acute type A aortic dissection is not rare and may contraindicate immediate surgery. Evaluating irreversible brain damage is critical in this setting and magnetic resonance imaging is a key determinant in the decision of selecting surgical over medical treatment for these patients.

Relative Mean Transit Time Predicts Subsequent Stroke in Symptomatic Carotid Occlusion
Mean transit time (MTT) measurements to assess cerebral hemodynamics are easily obtained by computed tomography and magnetic resonance imaging. We reviewed hemodynamic and clinical outcome data from the St. Louis Carotid Occlusion Study to determine if increased MTT was associated with an increased risk of stroke in patients with symptomatic complete carotid artery occlusion.

Predictors of Occult Atrial Fibrillation in One Hundred Seventy-One Patients with Cryptogenic Transient Ischemic Attack and Minor Stroke
Recent randomized studies have shown the potential of prolonged cardiac rhythm monitoring to detect silent paroxysmal atrial fibrillation (PAF) in patients with cryptogenic stroke. Our aim was to identify clinical and magnetic resonance imaging (MRI) factors that predict the detection of PAF during long-duration rhythm cardiac Holter (LDRCH) monitoring.

Accuracy of Stroke Diagnosis in Telestroke-Guided Tissue Plasminogen Activator Patients
The objective of the study is to assess the accuracy of final diagnosis in telestroke-guided tissue plasminogen activator (rt-PA) patients compared with bedside evaluation using computed tomography (CT) or magnetic resonance imaging (MRI) as a surrogate for final stroke diagnosis. The overall goal was to determine if telestroke had similar diagnostic accuracy as bedside evaluations in diagnosing rt-PA-treated patients.

Different Perfusion Patterns in a Patient with Acute Ischemic Stroke
A 29-year-old male patient with aphasia and mild weakness of the right arm arrived at the emergency room 4 hours after symptom onset. The computed tomography perfusion showed a typical delay in the time-based maps in the left occipital lobe and another hyperperfused area in the left frontal lobe. The follow-up magnetic resonance imaging confirmed cortical ischemic lesions in both areas. This case shows that besides hypoperfusion, hyperperfusion can also be found in the first stages of acute stroke, and it is highly suggestive of established ischemic lesions.

Feasibility of using magnetic resonance imaging as a screening tool for acute stroke thrombolysis
【Background】Feasibility of performing MRI first for suspected hyperacute stroke patients in real-world practice has not been fully examined. Moreover, most past studies of reducing door-to-needle time (DNT) in intravenous thrombolysis were conducted using CT. The aim of this study was to evaluat e the feasibility of an MRI-first policy and examine the effects of a quality improvement (QI) process for reducing DNT using MRI.

Assessment of DWI profile in acute ischemic stroke
【Background】The efficacy of endovascular therapy (EVT) in acute stroke has been established but the imaging criteria have not yet been assessed. “Malignant profile” is a magnetic resonance imaging (MRI) pattern that is associated with poor outcomes. We estimated this profile by diffusion wei ghted image (DWI) in patients treated with EVT.

Recurrent Stroke Due to Metastatic Pulmonary Tumor Emboli as an Important Clinical Entity
We present an autopsy case of repetitive stroke due to tumor emboli, indistinguishable from thromboembolism with a hypercoagulable state in its clinical course. A 72-year-old man diagnosed with stage IVA oropharyngeal squamous cell carcinoma received chemoradiotherapy. Follow-up imaging revealed mediastinal lymph nodes and pulmonary metastasis. One year later, the patient experienced right arm weakness, and brain magnetic resonance imaging showed acute ischemic lesions in multiple vascular territories.
