Effective ADAPT Thrombectomy in a Patient with Acute Stroke due to Cardiac Papillary Elastofibroma: Histological Thrombus Confirmation
A 75-year-old man with hypertension and atrial fibrillation was admitted to our emergency room with right-sided hemiplegia and complete aphasia (National Institutes of Health Stroke Scale [NIHSS] score = 18). A noncontrast computed tomography scan showed a slight hypodensity in the left insular region and a bright hyperdense sign in the M1 tract of the left middle cerebral artery (MCA). Angio-CT confirmed an occlusion of the M1 tract of the MCA. Magnetic resonance diffusion-weighted imaging/p erfusion-weighted imaging was obtained and revealed a mismatch in the left parietal cortical region.

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.

Time to Computerized Tomography Scan, Age, and Mortality in Acute Stroke
Time to computerized tomography (CT) is important to institute appropriate and timely hyperacute management in stroke. We aimed to evaluate mortality outcomes in relation to age and time to CT scan.

High Extent of Intracranial Carotid Artery Calcification Is Associated with Downstream Microemboli in Stroke Patients
Intracranial arterial calcification (ICAC) is frequently detected on head computed tomography and has been found to be associated with ischemic stroke by recent clinical studies.

Utility of Repeat Cerebrovascular Imaging among Hospitalized Stroke Patients
The purpose of this study is to evaluate the frequency and clinical utility of repeat cerebrovascular imaging with computed tomography angiography (CTA) of the head after contrast-enhanced magnetic resonance angiography (CE-MRA) of the head in acute stroke 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.

An Acute Ischemic Stroke Resulting from Aortic Dissection
A 39-year-old man with syncope and persistent dizziness was sent to stroke emergency. Patient's diffusion magnetic resonance imaging of brain showed acute ischemia in right cerebella and right occipital lobe, thus intravenous recombinant tissue plasminogen activator was given to him. However, the patient behaved rather restless with repeated complaint of back and thoracic pain. Further thorax computed tomography angiography confirmed that the underlying cause turned out to be aortic dissection.

Clinical Predictors of Stroke Mimics in Patients Treated with Recombinant Tissue Plasminogen Activator according to a Normal Multimodal Computed Tomography Imaging
Multimodal computed tomography imaging (MCTI) is increasingly used for rapid assessment of acute stroke. We investigated characteristics and final diagnoses of patients treated with recombinant tissue plasminogen activator (rt-PA) while admission imaging was unremarkable.

The Relation between Blood Count Parameters and Stroke in Patients with Intermediate Carotid Artery Stenosis
K öklü et al1 evaluated the correlation between blood count parameters, including the total white blood cell count (WBC), total neutrophil count, lymphocyte count, and neutrophil-to-lymphocyte ratio (NLR), and the risk of stroke in patients with intermediate carotid artery stenosis. They stated tha t an increased NLR value is an independent variable for carotid artery plaques to become symptomatic using the hemostatic parameters, carotid artery Doppler ultrasonography, and followed by computed tomography angiography.

Histology of Thrombectomy Specimen Reveals Cardiac Tumor Embolus in Cryptogenic Young Stroke
A 25-year-old woman presented with acute onset of right hemiplegia and global aphasia with National Institutes of Health Stroke Scale score of 19. Computed tomography angiography demonstrated occlusion of the left proximal middle cerebral artery. She was thrombolysed with intravenous recombinant tissue plasminogen activator (0.6 mg/kg) within 3 hours of onset of symptoms and was taken up for mechanical thrombectomy. The retrieved specimen appeared pale white and soft; histopathologic examination revealed a papillary neoplasm composed of papillae with hyalinized cores lined by endothelium, consistent with papillary fibro...

Limb Shaking Transient Ischemic Attacks with Normal Neurovascular Ultrasound may Herald Cardioembolic Stroke: ACase Report
We describe a 74 year-old woman with abrupt left arm jerking and normal urgent computed tomography scan, electroencephalography (EEG) as well as carotid and transcranial ultrasound. Two days later she developed an overt ischemic stroke, with left mesencephalon and left cerebellar hemisphere lesions at brain magnetic resonance imaging and paroxysmal atrial fibrillation at Holter-EKG.

Subacute Elevation of Plasma Level of Caspase-Cleaved Cytokeratin-18 is Associated with Hemorrhagic Transformation and Functional Outcome in Ischemic Stroke
Background: Caspase-cleaved cytokeratin-18 (CCCK-18) is an apoptosis marker. Here, we analyzed the relationship between plasma level of CCCK-18 in the acute and subacute stage of ischemic stroke and early and late functional outcome. Besides, correlation among CCCK-18 and complications, such as hemorrhagic transformation (HT) were also explored. Methods: Plasma concentration of CCCK-18 was investigated in 54 patients at admission and poststroke 72 hours. HT was evaluated by CT scans on 24 poststroke hours.
