There was no difference in the quality of care provided to stroke patients admitted during weekdays or weekends. There was no difference in the use of acute intervention on weekends and weekdays. Patients had similar outcomes and discharge disposition whether admitted on weekdays or weekends, except that those admitted on weekends had a significantly greater overall number of complications.

Neither imaging nor clinical presentation is sufficient to differentiate a sterile arachnoid cyst from recurrence of NCC. We present a case of symptomatic spinal intradural cyst enlargement 16 years after successful treatment of intracranial and spinal NCC with anti-helminthics.

Skeletal muscle symptoms and elevated creatine kinase (CK) levels have been consistently reported as part of the COVID-19 disease process. Previous studies have yet to show a consistent relationship between CK levels and skeletal muscle symptoms, disease severity, and death from COVID-19. The purpose of this study is to determine whether elevated CK is associated with a COVID-19 course requiring intubation, intensive care, and/or causing death. Inflammation antagonist Secondary objectives To determine if there is a relationship between elevated CK and (1) skeletal muscle symptoms/signs (2) complications of COVID-19 and (3) other diagnostic laboratory values.

This is a retrospective, single center cohort study. Data were collected from March 13, 2020, to May 13, 2020. This study included 289 hospitalized patients with laboratory-confirmed SARS-CoV-2 and measured CK levels during admission.

Of 289 patients (mean age 68.5 [SD 13.8] years, 145 [50.2%] were men, 262 [90.7%] were African American) with COVID-19, 52 (18.0%) reported myalgia, 92 (31.8%) reported subjective weakness, and 132 (45.7%) had elevated CK levels (defined as greater than 220 U/L). Elevated CK was found to be associated with severity of disease, even when adjusting for inflammatory marker C-reactive protein (initial CK OR 1.006 [95% CI 1.002-1.011]; peak CK OR 1.006 [95% CI 1.002-1.01]; last CK 1.009 [95% CI 1.002-1.016]; q = .04). Creatine kinase was not found to be associated with skeletal muscle symptoms/signs or with other laboratory markers.

Creatine kinase is of possible clinical significance and may be used as an additional data point in predicting the trajectory of the COVID-19 disease process.

Neurologists, ophthalmologists and emergency care physicians may be called upon to evaluate such patients. Monocular visual loss should be differentiated from the binocular involvement as the oetologies, investigations and management of such patients differ considerably. We report a case of monocular visual loss that involved predominantly one eye but affected the other side independently, albeit less frequently. A meticulous history, thorough general, neurological and ophthalmological examinations are necessary in such patients to identify the cause and to treat appropriately. Ocular ischemic syndrome (OIS) is due to chronic hypoperfusion of the structures supplied by ophthalmic artery leading to monocular visual loss. Stenosis of the ipsilateral internal carotid artery from a variety of causes is the main underlying mechanism. The first case of OIS was reported by Hedges in 1963 and the term was coined later by Barry and Magargal. Ocular ischemic syndrome is an important differential diagnosis to consider especially in older people and those with vascular risk factors. An overview of important differential diagnosis, clinical features and treatment of OIC are discussed in this article. A multidisciplinary team is optimal for the management of ocular ischemic syndrome.Amyloid-beta related angiitis (ABRA) is a rare central nervous system inflammatory and vasculitic process. It is seen in patients with cerebral amyloid angiopathy (CAA) and thought to be mediated by an autoimmune reaction against cerebrovascular β-amyloid. We describe the case of a patient with ABRA with clinical information and brain imaging over a 10-year period. The patient was hospitalized in 2018 for altered mental status, paranoia and hallucinations. Her symptoms started in 2009 with an episode of vertigo and loss of consciousness. From 2011-2019, she had multiple episodes of transient focal neurological deficits with overall cumulative progressive decline in cognition and functional status. Retrospective and comparative reviews of brain magnetic resonance imaging (MRI) from 2009-2019 showed waxing and waning vasogenic cerebral edema with overall progression of white matter hyperintensities and peripheral micro-hemorrhages consistent with inflammatory CAA. Re-examination of a brain biopsy from 2009 showed ABRA, and immunostaining was positive for β-amyloid. She was treated with intravenous steroids with minimal symptomatic improvement. She was lost to our follow-up after hospital discharge. We describe the temporal progression of ABRA through serial brain imaging over a 10-year period. To our knowledge, this is the longest published follow-up duration of ABRA. The patient in our case had severe cognitive impairment and disability despite treatment with steroids.Intrathecal methotrexate (IT MTX) resulting in severe adverse events including life-threatening cerebral edema is not well described. We report a rare case of death in a 37-year-old BRCA1+ woman with metastatic triple-negative breast cancer status post mastectomy following administration of IT MTX for leptomeningeal carcinomatosis. Within the 24 hours after intraoperative IT MTX delivery, she developed neurologically devastating diffuse cerebral edema leading to uncal and cerebellar tonsillar herniation. This case report highlights a rare but devastating side effect of IT MTX.A vascular malformation is an abnormal development of blood vessels that can be found in arteries, veins, or the lymphatic system. While pathology such as aneurysms, arteriovenous malformations (AVMs), dissections, and dolichoectasia have been documented frequently and linked to an increased incidence of stroke, we present a rare finding of a ‘corkscrew’ appearance of the basilar artery causing recurrent posterior circulation symptoms. Imaging during 3 separate hospitalizations showed recurrent acute strokes within the basilar artery vascular territory. A conventional cerebral angiogram revealed a corkscrew appearance of the basilar artery with no dilatation, outpouching, or aneurysm.

Magnetic resonance imaging (MRI) is safe for most patients with cardiovascular implantable electronic devices (CIEDs). However, patients presenting with acute ischemic stroke or transient ischemic attack (AIS/TIA) who have CIEDs may undergo MRI less frequently than patients without devices. We assessed contemporary use of MRI for patients with AIS/TIA and the effect of a recent coverage revision by the Center for Medicare and Medicaid Services (CMS) on MRI utilization.

Using Optum

claims data from January 2012 to June 2019, we performed an interrupted time series analysis of MRI utilization during AIS/TIA hospitalizations with the April 2018 CMS coverage revision serving as the intervention. For patients treated after the coverage revision, we used multivariable logistic regression to determine the association between lack of CIED and MRI utilization for AIS/TIA.

We identified 417,899 patient hospitalizations for AIS/TIA, of which 30,425 (7%) had a CIED present (CIED vs non-CIED patients age 77.6 ± 9.8 vs 72.7 ± 12.3 years; 45.5% vs 54.3% female). From 2012 to 2019, annual MRI utilization increased from 3% to 20% for CIED patients and 58% to 66% for non-CIED patients. The CMS coverage revision was associated with a 4.2% absolute additional increase in MRI utilization for CIED patients. Non-CIED patients treated after the CMS coverage revision were substantially more likely than CIED patients to undergo MRI (adjusted OR 6.7, 95% CI 6.3-7.1, P<.001).

MRI utilization has increased for stroke patients with CIEDs but remains far lower than in similar patients without devices.

The explanation for this phenomenon is unknown but may be due to a combination of effects involving disrupted interhemispheric inhibitory connections and epileptogenic changes involving chronically infarcted tissue.Painful Hand Seizures are a rarely reported form of secondary sensory seizures (SSS) characterized by painful, bilateral sensorimotor hand involvement and preserved consciousness. We report our case to aid neurologists in recognizing SSS as an atypical presentation of seizures.Cerebral cavernous malformations (CCMs) are usually intraparenchymal lesions commonly associated with intraparenchymal hemorrhage. Extra-axial Lesions are uncommon and have rarely been reported as the cause of aneurysmal like subarachnoid hemorrhage (SAH). We present a 33-years-old female with a past medical history significant for hypertension who presented with acute onset head and neck pain after bending over. En route to the hospital, she had abnormal motor movements suggestive of seizures. Computed tomography (CT) of the head was significant for diffuse aneurysmal like SAH. Head CT angiography (CTA) and catheter digital subtraction angiography (DSA) were both negative for aneurysm. Magnetic resonance imaging (MRI) of the brain showed susceptibility artifact in the right parafalcine frontal lobe suspicious for underlying CCM. This lesion was in the area suspected of having an aneurysm on CT head. The patient was diagnosed with SAH secondary to cavernous malformation mimicking aneurysmal etiology. This case is important as it serves as a good reminder to consider cavernous malformations in the differential in patients presenting with angiogram negative SAH. Diagnosis of this entity has treatment implications including discontinuation of calcium channel blockers if initiated, discussion about duration of anti-seizure medication, in addition to consideration for surgical intervention in select populations.The use of e-cigarettes is gaining popularity despite knowing about cardiovascular health risks. Cases of intentional or accidental intoxication following ingestion of the refill solution are also a growing concern. Most of these cases were fatal and related to cardiac arrest and hypoxic brain injury. We report the case of a 54-year-old woman who developed bilateral acute ischemic stroke in the anterior and posterior cerebral circulation following intentional oral intake of e-liquid nicotine refill solution. The diagnostic work-up concluded an etiology of embolic stroke of undetermined source, most likely of cardiac origin. We assume that sympathetic overactivation lead to temporary cardiac arrhythmia and subsequent thrombi formation. Moreover, we discuss several additional pathogenic aspects of oral intake of e-liquid refill solution for the development of central nervous system pathology. This case expands the clinical spectrum of health hazards associated with the introduction of e-cigarettes and raises awareness of the need for preventive measures.
