Amusia for Pitch Caused by Right Middle Cerebral Artery Infarct
A 61-year-old right-handed man with hypertension and dyslipidemia noted that he was singing along to classic rock songs on his car radio, but his voice was off pitch. Six days later, a magnetic resonance imaging scan of his brain revealed a cerebral infarct of the right temporal parietal cortex and insula. Case reports of the precise anatomic correlates of disordered pitch musical processing have been few and fragmentary. The anatomic involvement of our case coincides with the areas of involvement in 3 previously reported cases. Increased awareness of amusia as a rare clinical presentation of stroke should lead to earlier stroke intervention.

Simultaneous onset of myocardial infarction and ischemic stroke in a patient with atrial fibrillation: Multiple territory injury revealed on angiography and magnetic resonance
An 84-year-old man with a history of hypertension and paroxysmal atrial fibrillation (AF) who received no anticoagulant drugs experienced acute chest pain and transient loss of consciousness. He was transferred to our emergency room. His initial electrocardiogram showed sinus rhythm with ST-segment elevation in the I, aVL, and V1–V6 leads. His blood pressure was 158/92mmHg and his pulse was regular at 70beats per minute. A chest radiograph showed increased heart size and pulmonary vascular congestion. His troponin T level was elevated (more than 0.1ng/mL). He was diagnosed with ST-elevation myocardial infarction (MI) and...

Successful treatment with intravenous recombinant tissue plasminogen activator in an acute stroke patient presenting with hemiballism.
Authors: Bembenek JP, Bilik M, Członkowska A Abstract A 79-year-old woman with hypertension was evaluated 3 hours and 20 minutes after the sudden onset of left-sided weakness which lasted about 15 minutes and was followed by involuntary, coarse, flinging movements of the left extremities (hemiballistic), occurring every few minutes, and facial asymmetry. Brain computed tomography revealed no abnormalities. The patient received intravenous thrombolysis with 0.9 mg/kg of alteplase 4 hours after the symptom onset. Involuntary movements and central facial nerve paresis subsided within 48 hours of the thrombolysis. Mag...

Report of cold agglutinins in a patient with acute ischemic stroke
Conclusion: We report here the first case of cerebral infarction probably due to the cold agglutinin disease. The underlying mechanism of cold agglutinins in the pathogenesis of acute ischemic stroke needs to be investigated further.

Pontine Warning Syndrome: A Chameleon of Ischemic Stroke
Conclusions: PWS is a diagnostic and management challenge for the clinician. Because of its low incidence, this syndrome has been underestimated and understudied. There is, currently, no standard treatment for this condition; however, it is paramount, during treatment, that hypotension/hypoperfusion be avoided, with the goal being asymptomatic normotension to permissive hypertension. The probable mechanism of disease is hypoperfusion due to basilar artery branch disease and perhaps cerebral vascular dysregulation in the affected area.

Atypical presentation of giant cell arteritis in a patient with vertebrobasilar stroke: A case report
Rationale: Giant cell arteritis (GCA) is known to present with typical manifestations like temporal headache and visual abnormalities. However, several cases with atypical manifestations were reported. Stroke occurs in 3% to 7% of patients with GCA. Patient concerns: A 67-year-old male patient with known hypertension presented with somnolence, disorientation and mild bilateral limb ataxia. The magnetic resonance imaging showed multiple acute infarctions in the territory of the vertebrobasilar system with occlusion of the left vertebral artery. Diagnosis: Ten months later, during a routine neurovascular follow-up, r...

Reperfusion Injury on Magnetic Resonance Imaging After Carotid Revascularization Brief Reports
Conclusions— HARM after carotid revascularization is not uncommon. Symptomatic HARM was associated with old age, underlying leukoaraiosis, and postprocedural high blood pressure.

Difference in Aneurysm Characteristics Between Ruptured and Unruptured Aneurysms in Patients With Multiple Intracranial Aneurysms Clinical Sciences
Conclusions— Aspect ratio ≥1.3 and irregular shape are associated with aneurysm rupture independent of aneurysm size and location, and independent of patient characteristics. Additional studies need to assess to what extent these factors increase the risks of rupture of small aneurysms in absolute terms.

Diagnostic Accuracy and Risk Factors of the Different Lacunar Syndromes
Conclusions: The clinical diagnosis of patients with lacunar syndromes is inaccurate, especially among patients with sensorimotor syndrome. DWI is mandatory for obtaining an accurate diagnosis of the infarct.

Prevalence and Clinicoradiological Analyses of Patients with Alzheimer Disease Coexisting Multiple Microbleeds
Conclusions: The present study indicated that the prevalence of multiple MBs was 17% in Japanese AD patients. The clinicoradiological profile suggested severe degree of CAA in patients with multiple L MBs (9%) and hypertension and aged changes in patients with multiple D/I MBs (8%). T2*-weighted imaging is a useful tool for evaluating degree of CAA and hypertensive vascular changes. We should pay more attention to management and care in AD patients with multiple MBs.

Relation between Cardiovascular Disease Risk Markers and Brain Infarcts Detected by Magnetic Resonance Imaging in an Elderly Population
Established cardiovascular risk markers, such as hypertension, are associated with increased risk of brain infarcts. The newer markers N-terminal pro-brain natriuretic peptide, troponin I, C-reactive protein, and cystatin C may affect the risk of cardiovascular events and potentially, thereby, also stroke. We investigated the association between established and new risk markers for cardiovascular disease and brain infarcts detected by magnetic resonance imaging (MRI) at age 75.

Ambulatory Arterial Stiffness Index Is Not Associated With Magnetic Resonance Imaging Markers of Cerebral Small Vessel Disease in Lacunar Stroke Patients
Ambulatory arterial stiffness index (AASI) is associated with microvascular damage in other organs, but the association with microvascular brain damage is unknown. The association of AASI with magnetic resonance imaging (MRI) markers of cerebral small vessel disease in 143 patients with lacunar stroke was investigated. We performed 24‐hour ambulatory blood pressure monitoring and scored the presence of lacunes, white matter hyperintensities, perivascular spaces, and cerebral microbleeds on brain MRI. In logistic regression analyses, AASI was associated with white matter hyperintensities, but, after adjustment for age and...

Effects of Induced Hypertension on Cerebral Perfusion in Delayed Cerebral Ischemia After Aneurysmal Subarachnoid Hemorrhage: A Randomized Clinical Trial Brief Reports
Conclusions— Change in overall CBF did not differ to a statistically significant extent between the groups. Based on our results, 225 to 250 patients per group are needed to find a statistically significant difference in change in overall CBF between induced hypertension and no hypertension.
