Imaging findings of adult-onset mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome is poorly documented. The authors present a 48-year-old woman with subacute onset of word-finding difficulties and right arm stiffness. Magnetic resonance imaging performed 2 weeks prior revealed left temporal lobe diffusion and fluid-attenuated inversion recovery hyperintensity predominantly involving the cortex. The apparent diffusion coefficient map showed preserved signal in the temporal cortex...

Stroke occurs due to the interruption of blood flow to the brain and it is divided into ischemic and hemorrhagic. In the ischemic strokes, while the most commonly affected vessel is median cerebral artery (MCA), it is particularly affected bilateral posterior cerebral artery (PCA) is very rare condition. In this study, a case of sudden loss of vision and bilateral occipital infarct associated with bilateral vertebral system pathology and methylene tetrahydrofolate reductase (MTHFR) gene mutation were reported...

BACKGROUND: Based on a case report, the authors reviewed the data about involuntary emotional expression disorder (IEED). IEED includes the syndromes of pathological laughing and crying (PLC) and emotional lability (EL). PLC is a rare disorder of emotional expression characterized by relatively uncontrollable episodes of laughter and crying or both that do not have an apparent motivating stimulus. CASE PRESENTATION: Authors report the case of a 59-year-old man who presented with recurrent episodes of PLC of approximately 2 min duration, consisting of accelerated breathing, emission of guttural, snoring sounds, frowning of the eyebrows, followed by laughter accompanied by motor restlessness of all four limbs...

BACKGROUND: Intracerebral hemorrhage is the most feared complication of intravenous thrombolysis for acute ischemic stroke. Such hemorrhage usually occurs within or at the margin of ischemic or manifestly infarcted brain tissue. A patient with Trousseau syndrome who developed multiple extra-ischemic hemorrhages following intravenous thrombolysis is described. CASE DESCRIPTION: An 80-year-old Japanese man with no other underlying disease was diagnosed with unresectable advanced lung cancer (stage IV) without brain metastasis and had not yet been treated...

Intracranial atherosclerotic disease is a major cause of ischemic stroke. Stenting and aggressive medical management for preventing recurrent stroke in intracranial stenosis was terminated prematurely due to a high stroke and death rate in patients randomized for intracranial stent placement. However, for some patients, angioplasty and/or stent placement remains the best approach. Flow diverters (FDs) are designed to produce a hemodynamic flow diversion by constituting a laminar flow pattern in the parent artery and are mainly used in non-ruptured complex wide-neck aneurysms as well as in ruptured aneurysms...

Asterixis is not yet considered a common neurological sign of cerebellum infarction, and the pathogenic mechanism for asterixis remains elusive. We report a 58-year-old male with moderate hypertension who presented to our emergency department for acute headache in both cervical and occipital regions of the left side. About 2 hours later the patient developed ipsilateral asterixis in the upper left limb; 3 days later the asterixis disappeared. Magnetic resonance imaging of the brain disclosed cerebellar infarctions at the left superior cerebellar artery...

Free floating thrombus in the carotid artery is a well-known phenomenon, though relatively rare. We present a case in which we performed open surgery and achieved successful retrieval of the thrombus. A 40 year-old male patient presented with ischemic stroke and mild left hemiparesis. Computerized tomography and magnetic resonance imaging showed infarction in the right parieto-occipital area. Carotid Doppler study showed carotid stenosis on the right side. Further investigation with CT angiography of the neck vessels confirmed significant carotid artery occlusion with a free-floating thrombus in the internal carotid artery...

Reversible cerebral vasoconstriction syndrome (RCVS) has reversible multifocal narrowing of the cerebral arteries. Respiratory alkalosis in high altitude studies cause impairment of the central nervous system, presumably by cerebral vasoconstriction. A 54 year-old woman presented with a 1-week of throbbing headache around her forehead while travelling in moderately high altitude, during a windy winter. Sudden severe headache had progressed and developed bilateral lower visual fields defect along with mild weakness of her right leg on the next day...

Ischemic stroke is rare in children, most of which occur in the supratentorial brain, and infratentorial infarcts are very rare. Some clinical manifestations may be similar but others such as ataxia and cranial nerve palsy are more specific. Vertebral artery dissection is the most frequent cause of stroke in the vertebrobasilar territory, but the cause most often remains unknown in children. We report three cases of infratentorial stroke in children. The first observation concerns a 4-year-old boy brought to medical attention because left hemicorporal motor deficit associated with ataxia following a minor cranial traumatism...

A method for long-term, repeated, semi-quantitative measurements of cerebral microflow at the same region of interest (ROI) with high spatial resolution was developed and applied to mice subjected to focal arterial occlusion. A closed cranial window was chronically implanted over the left parieto-occipital cortex. The anesthetized mouse was placed several times, e.g., weekly, under a dynamic confocal microscope, and Rhodamine B-isothiocyanate-dextran was each time intravenously injected as a bolus, while microflow images were video recorded...

A 43-year-old woman presented with weakness in her left arm and leg. She had noticed headache persisting for 2 weeks in her right occipital area 6 weeks prior to the onset of the weakness. Cranial diffusion-weighted MR image demonstrated acute infarction in the right medial part of medulla oblongata. Cerebral angiography revealed pearl and string sign in the right intracranial vertebral artery. Magnetic resonance T1-weighted image obtained when the patient complained of left-sided weakness showed a high intensity area in right vertebral artery corresponding to intramural hematoma...

This study was designed to assess that mouse pial and cortical microcirculation can be monitored in the long term directly in the area of focal ischemia, using in vivo fluorescence microscopy. A closed cranial window was placed over the left parieto-occipital cortex of C57BL/6J mice. Local microcirculation was recorded in real time through the window using laser-scanning confocal fluorescence microscopy after intravenous injection of fluorescent erythrocytes and dextran. The basal velocity of erythrocytes through intraparenchymal capillaries was 0...

A 60-year-old man presented with the chief complaint of seeing a blurred area just up and to the left of the center of his vision. The patient noted this visual field defect immediately after he awoke from a cardiac electrophysiologic study with a catheter ablation procedure. On neuro-ophthalmologic testing, a small scotoma was present superior and left of fixation in both eyes. MRI showed a small irregular area of abnormal signal in the right occipital lobe consistent with an ischemic lesion. To the best of our knowledge, this represents the first case report of a homonymous visual field defect secondary to an occipital lobe infarction following a cardiac catheter ablation procedure...

A 70-year-old patient with a history of hypertension and hypercholesterolemia was referred for evaluation of necrotic toes. The patient had a history of several cerebrovascular accidents during the previous month. Initially, she developed sudden-onset left upper extremity weakness which, over the ensuing 4 days, progressed to complete left-sided weakness. This was followed by the development of acute dysarthria. A transesophageal echocardiogram revealed moderate left ventricular hypertrophy, several vegetations on her tri-leaflet aortic valve associated with moderate aortic regurgitation, and a large right atrial thrombus with a mobile component...
