Intravenous Thrombolysis in Posterior Circulation Stroke
Conclusions: Up to date, no data about PCIS and IVT are available from RTCs. Based on limited results from retrospective clinical studies and case series, IVT is safer for use in PCIS than in ACIS. Patients with brainstem ischemia, vertebral artery occlusion, and absence of basilar or posterior cerebral artery occlusion could be considered for treatment with IVT even in borderline cases. Time to IVT in PCIS seems to be a less crucial factor than in ACIS. IVT for PCIS may be beneficial even after 4.5 h from symptom onset.

Neurological Involvement in Primary Systemic Vasculitis
Conclusion Neurological involvement is a common complication of PSV (Table 1), and neurologists play an important role in the identification and diagnosis of PSV patients with otherwise unexplained neurological symptoms as their chief complaint. This article summarizes the neurological manifestations of PSV and hopes to improve neuroscientists' understanding of this broad range of diseases. TABLE 1 Table 1. Common CNS and PNS involvements of primary systemic vasculitis. Author Contributions SZ conceived the article and wrote the manuscript. DY and GT reviewed and edited the manuscript. All authors ...

Discrepancy between perfusion- and diffusion-weighted images in ischemic stroke: A case report
Rationale: With the development of multi-slice computed tomography (CT) technology, perfusion CT angiography (p-CTA) is now widely used for the diagnosis of acute cerebral infarction. Although p-CTA has the advantage of distinguishing between an ischemic penumbra and an infarct core, more research is needed with respect to its clinical use. Patient concerns: A healthy 36-year-old man experienced sudden dizziness while swimming. His dizziness persisted irrespective of the change in position, and then improved during transport. He had no neurological abnormality when he arrived at the emergency room. Diagnoses: CT pe...

Ataxia and Headache in a Child: A Case of Acute Cerebellar Infarction
Abstract: A 4-year-old female patient presents to the pediatric emergency department with acute onset of ataxia and occipital headache. Initial investigation, including computed tomography imaging, failed to demonstrate any focal neurologic lesion. Subsequent studies, however, reveal an acute thrombosis of the superior cerebellar artery. Further work up identified the likely causative factor to be a heterozygous mutation at the methylene tetrahydrofolate reductase gene. In this case report, we will discuss the work-up of pediatric ataxia, the evaluation and management of cerebrovascular accidents in children, and the assoc...

Paradoxical Embolism in the Setting of Inferior Vena Cava Filter Removal (P1.283)
Conclusions:Although clinically relevant events secondary to IVC filter migration and fracture are rare, they can be life-threatening. Care should be taken when choosing to place these devices, and alternative therapies should be considered when possible. They should be removed when no longer needed, as fracture rates are increased with longer dwell times. Up to half of complications can be avoided with retrieval within 3 months.Disclosure: Dr. Yost has nothing to disclose. Dr. Klaas has nothing to disclose.

Acute Hearing Loss Caused by Decreasing Anterior Inferior Cerebellar Arterial Perfusion in a Patient with Vertebral Artery Stenosis
We report a case of bilateral hearing loss caused by decreased vascular flow in the anterior inferior cerebellar artery (AICA) territory. A 74-year-old man who experienced right hearing loss 5 months ago presented with bilateral deafness and right cerebellar ataxia; however, no ischemic lesion was detected in the bilateral AICA area. After stroke treatment, hearing loss was improved. One month later, we obtained blood flow improvement in the left AICA territory on single –photon-emission computed tomography and vertebral artery stenosis on magnetic resonance angiography.

Vertebral Artery Dissection Causing Stroke After Trampoline Use
Conclusions: Vertebral artery dissection is a relatively common cause of stroke in the pediatric age group. Trampoline use has been associated with significant risk of injury to the head and neck. Patients who are small and/or young are most at risk. In this case, minor trauma secondary to trampoline use could be a possible mechanism for vertebral artery dissection and subsequent strokes. The association in this case warrants careful consideration because trampoline use could pose a significant risk to pediatric users.

E-088 successful mechanical thrombectomy for basilar artery stroke in a 22-month old child
We present the case of a 22-month-old with basilar artery occlusion successfully treated with mechanical thrombectomy.The patient presented to the emergency department with altered mental status and gait ataxia. She "felt limp", her breathing was shallow, and her gaze dysconjugate. Her medical history included congenital heart defects with multiple cardiac procedures.In the emergency department, she fell with attempted ambulation. Labs were normal, as was a chest x-ray, and EKG. A computerized tomography (CT) scan of the head suggested left cerebellar hemisphere attenuation. The differential included arrhythmia, stroke, or...

Stroke of a cardiac myxoma origin
Conclusion: Cardiac myxoma stroke is rare. Often does it affect young females. For an improved diagnostic accuracy, magnetic resonance imaging of the brain and echocardiography are imperative for young stroke patients in identifying the cerebral infarct and determining the stroke of a cardiac origin. Immediate thrombolytic therapy may completely resolve the cerebral stroke and improve the neurologic function of the patients. An early surgical resection of cardiac myxoma is recommended in patients with not large territory cerebral infarct.

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...

Early Diagnosis of Posterior Fossa Stroke with Brainstem Evoked Potentials (I1-3B)
Conclusion: BAP is more sensitive for diagnostic purposes towards posterior fossa small strokes and should be considered in patients when the initial MRI brain is negative. This will allow for correct diagnosis and treatment regimen without causing a delay for the patient.Disclosure: Dr. Duggal has nothing to disclose. Dr. Ahmed has nothing to disclose.

Inaugural Cerebral Sinovenous Thrombosis Revealing Homocystinuria in a 2-Year-Old Boy
We report on the case of a 2-year-old boy with mild psychomotor delay, who presented with nonfebrile acute ataxia. A brain computed tomographic (CT) scan showed complete thrombosis of the superior sagittal sinus, confirmed by magnetic resonance angiography and associated with a right frontal hemorrhagic infarction. Systematic screening for thrombophilia revealed homocystinuria linked to cystathionine β-synthase deficiency with underlying compound heterozygosity. The evolution was favorable after anticoagulant therapy, specific diet, and vitamin supplementation. This case is of interest because of the unusual clinical ...
