Pediatric giant cell glioblastoma mimicking hemorrhage secondary to ischemic stroke
An eight-year-old girl presented with headaches, nausea, and diminished consciousness. Initial computed tomography (CT) showed an intracerebral hemorrhage with mass effect (Fig. 1). A four-vessel catheter angiogram ruled out vascular malformations, aneurysms or vasculitis. On magnetic resonance imaging (MRI), the hemorrhage had both an acute and sub-acute bleeding component (Fig. 2A and 2B). Anteriorly of the hemorrhage, a region with weak contrast enhancement was noted (Fig. 2C and 2D). This was interpreted as reactive contrast enhancement.

The Course of Headache in Patients With Moderate-to-Severe Headache Due to Aneurysmal Subarachnoid Hemorrhage: A Retrospective Cross-Sectional Study.
CONCLUSIONS: The course of headache in patients with aSAH continuously improved during the 12 months of follow-up. Headache improvement might be expected in patients who were treated with EVT and in those who did not have previous stroke or headache. PMID: 26129830 [PubMed - as supplied by publisher]

Stroke in a Young Swimmer
Conclusions: Important differential diagnoses of cervicocephalic arterial dissection include other vascular or neurological causes of head and neck pain and/or local neurological syndromes and other causes of brain ischemia such as cardiac emboli, atherosclerosis, and vasculopathy of brain vessels. It is important that sports medicine practitioners pay attention to this less-diagnosed cause of stroke in young athletes.,Introduction: Arterial dissections are important causes of stroke in the young population. Dissection has been reported in association with some sports. It seems that this report is among the first ones of t...

Refractory status epilepticus due to SMART syndrome
Conclusions Taking into account clinical evolution and ictal neuroimaging studies, status epilepticus could explain the origin of these episodes in SMART syndrome. Although most patients have reversible symptoms, in some cases, aggressive treatment to avoid sequelae is needed. This article is part of a Special Issue entitled “Status Epilepticus”.

CT within 6 hours of headache onset to rule out subarachnoid hemorrhage in nonacademic hospitals
Conclusions: Our results support a change of practice wherein a lumbar puncture can be withheld in patients with a head CT scan performed <6 hours after headache onset and reported negative for the presence of SAH by a staff radiologist in the described nonacademic setting.

Diagnosis of Acute Stroke.
Abstract Stroke can be categorized as ischemic stroke, intracerebral hemorrhage, or subarachnoid hemorrhage. Awakening with or experiencing the abrupt onset of focal neurologic deficits is the hallmark of the diagnosis of ischemic stroke. The most common presenting symptoms of ischemic stroke are speech disturbance and weakness on one-half of the body. The most common conditions that can mimic a stroke are seizure, conversion disorder, migraine headache, and hypoglycemia. Taking a patient history and performing diagnostic studies will usually exclude stroke mimics. Neuroimaging is required to differentiate ischemi...

Myriad Manifestations of a Global Infectious Disease (I7-5A)
CONCLUSIONS: This case exhibits the myriad manifestations of tuberculosis in one patient; including meningitis, vasculitis, and tuberculomas. It also highlights that insular stroke in the non-dominant hemisphere could affect the cardiovascular-autonomic system.Disclosure: Dr. Prabhu has nothing to disclose.

Is CT Scan in Patients with Suspected TIA Necessary: A quality improvement initiative (P2.307)
CONCLUSIONS: Patients with suspected TIA and low risk for intracranial hemorrhage could undergo MRI rather than CT plus MRI. This practice would prevent unnecessary radiation dose from CT, decrease cost, and increase availability of the CT scanner for other patients in the ED.Disclosure: Dr. Baghshomali has nothing to disclose. Dr. Bishop has nothing to disclose. Dr. Hiestand has nothing to disclose. Dr. Reynolds has nothing to disclose. Dr. Bushnell has nothing to disclose.

Detection of Basilar Artery Dissection by Ultrasound
We report a case of a 45-year-old woman with unusual headache 1 week before admission. After cerebrovascular ultrasound, a basilar artery dissection was supposed despite the normal neurologic, cerebrospinal fluid, and computed tomography findings. On a follow-up color-coded duplex sonography (1 month after the onset), reperfusion was detected in the vertebral and basilar arteries, but residual high-grade stenosis of the basilar artery was also present.

Acute Lyme Neuroborreliosis With Transient Hemiparesis and Aphasia
We report a case of a female teenager presenting with sudden-onset aphasia and transient right-sided faciobrachial hemiplegia, along with headache and agitation. Ischemia, vasculitis, or another structural lesion was excluded by brain imaging. Toxicologic evaluation results were negative. Cerebral perfusion computed tomography and electroencephalography showed left parietotemporal brain dysfunction. Lumbar puncture result, although atypical, suggested bacterial infection and intravenous ceftriaxone was initiated. Finally, microbiological cerebrospinal fluid analysis revealed Lyme neuroborreliosis, showing specific intrathe...

Teaching NeuroImages: Cortical blindness following acute obstructive hydrocephalus by a colloid cyst
A 46-year-old woman was admitted for acute headache, postseizure confusion, and visual loss. Urgent head CT scan showed obstructive hydrocephalus due to a colloid cyst (figure 1). External ventricular drains inserted emergently demonstrated CSF under pressure, above 40 mm H2O. MRI confirmed the suspected diagnosis of a colloid cyst and highlighted bilateral occipital lobe infarcts (figure 2). CT angiography showed no thrombosis of the posterior cerebral arteries (PCAs). After neurosurgical excision of the colloid cyst, the patient remained blind. The presumed mechanism of infarction was acute compression of the PCAs agains...
