Miller fisher syndrome presenting with prodromal thunderclap headache
Conclusions Although not radiographically confirmed, we postulate the headache may have been due to reversible cerebral vasoconstriction syndrome (RCVS), given the characteristics of the headache and dramatic response to nimodipine. Although headache is infrequently observed in Miller Fisher syndrome, the exact aetiology is unclear and there has been no previously reported association with RCVS.

Acute Stroke differential diagnosis: stroke mimics
Publication date: Available online 5 May 2017 Source:European Journal of Radiology Author(s): Pedro Vilela Stroke mimics (SM) are non-vascular conditions that present with an acute neurological deficit simulating acute ischemic stroke and represent a significant percentage of all acute stroke hospital admissions. The most common clinical SM includes conversion/functional (psychiatric disorder); seizures and postictal paralysis; toxic-metabolic disturbances; brain tumours; infections, and migraine. Imaging is essential for SM recognition, being Diffusion weighted imaging (DWI), perfusion imaging and angiographic studies ve...

Primary Angiitis of the Central Nervous System Clinical Sciences
Conclusions—Adult primary angiitis of the central nervous system is a heterogenous disease, with multiterritorial, distal, and bilateral acute stroke being the most common pattern of parenchymal lesions found on magnetic resonance imaging. Our findings suggest a higher than previously thought prevalence of hemorrhagic transformation and other hemorrhagic manifestations.

Success of Intravenous Infusion of Verapamil for Refractory Vasospasm in aneurysmal Subarachnoid Hemorrhage (P2.291)
Conclusions:This report indicates that intravenous continuous infusion of verapamil may be used for rescue therapy in transiently responsive cerebral vasospasm to IA verapamil. This therapy did not seem to compromise hemodynamic stability or increase ICP.Disclosure: Dr. Mehta has nothing to disclose. Dr. Kulhari has nothing to disclose. Dr. Z Arango has nothing to disclose.

A rare cause of stroke in young: PHACE syndrome (P1.253)
Conclusions:Neurocutaneous syndromes are typically diagnosed in childhood and can be a rare cause of stroke in young. Our patient suffered an ischemic stroke secondary to sequelae of undiagnosed PHACE syndrome. Early identification of neurocutaneous syndromes allows for proper surveillance, evaluation, and preventative education for development of complications.Disclosure: Dr. Fitzgerald has nothing to disclose.

Recurrent transient hemiparesis and a novel ATP1A2 mutation (P3.220)
Conclusions:This case identifies a novel, potentially pathogenic mutation of the ATP1A2 gene corresponding to a phenotype of a rare migraine variant and contributes to our evolving understanding of migraine molecular genetics and pathophysiology.Study Supported by:Disclosure: Dr. Stredny has nothing to disclose.

Eagles Syndrome: Viewing a Rare Disorder from a New Perspective (P1.297)
Conclusions:This case not only exhibits an uncommon etiology for stroke, but also introduces an innovative method to visualize complex neuroanatomy. Given the relatively low cost and harmless creation of the model, this option may prove beneficial in other similar cases.Disclosure: Dr. Shah has nothing to disclose.

Hypoperfusion, vascular pruning, and transient hemiparesis mimicking stroke in transient erythroblastopenia of childhood (P4.161)
Conclusions:The patient’s transient cerebrovascular and electrophysiologic abnormalities are consistent with those described in the literature for hemiplegic migraine. However, he did not meet International Headache Society criteria for hemiplegic migraine, such as headache with presentation or recurrent events. We hypothesize that transient vascular narrowing and resultant hypoperfusion, compounded by cerebral hypoxia from significant anemia, may explain the transient neurologic symptoms concurrent with anemia in TEC.Disclosure: Dr. Calahan has nothing to disclose.

Moyamoya Syndrome Secondary to Vasculopathy in Down Syndrome: A Case Report and Literature Review (P3.071)
Conclusions:Our case suggests the angiographic pattern in Moyamoya syndrome due to Down syndrome vasculopathy may begin in the middle cerebral artery as it occasionally can in idiopathic Moyamoya disease with sparing of the supraclinoid internal carotid artery. Further studies are warranted to compare the angiographic and clinical course of Moyamoya syndrome due to Down syndrome vasculopathy with that of idiopathic Moyamoya disease.Disclosure: Dr. Shehabeldin has nothing to disclose.

Oculomotor Nerve Palsy in a Patient with a Ruptured Middle Cerebral Artery Aneurysm.
We describe a case of acute oculomotor nerve palsy caused by a ruptured middle cerebral artery (MCA) aneurysm. A 59-year-old female presenting with headache and nausea was admitted to our hospital. Her consciousness was alert, and had no other neurological deficit without left oculomotor nerve palsy. A computed tomography (CT) showed SAH extending from left sylvian cistern to basal cistern. CT angiography revealed a left MCA aneurysm which protruded toward internal carotid artery. The patient was successfully treated with surgical clipping. The oculomotor nerve palsy resolved immediately after the surgery. Perioperative ra...

Management of aneurysmal subarachnoid hemorrhage: State of the art and future perspectives.
CONCLUSIONS: Even though no single pharmacological agent or treatment protocol has been identified, the main therapeutic interventions remain ineffective and limited to the manipulation of systemic blood pressure, alteration of blood volume or viscosity, and control of arterial dioxide tension.

Glucocorticoid-associated worsening in reversible cerebral vasoconstriction syndrome
Conclusion: Patients with RCVS at risk for worsening can be identified on basis of baseline features. Iatrogenic factors such as glucocorticoid exposure may contribute to worsening.

Teaching NeuroImages: Intracranial vertebral dissection in a 15-year-old boy with sickle cell disease
A 15-year-old boy with sickle cell disease became unresponsive after sudden-onset headache. There was no antecedent trauma. A head CT scan demonstrated subarachnoid hemorrhage at the medulla (figure). Magnetic resonance angiography of the head and neck identified the patient's known bilateral internal carotid artery stenosis (a moyamoya-like arteriopathy associated with stroke in sickle cell disease) and a new right vertebral artery dissection, which was confirmed on conventional angiography (figure). Prior MRI performed as part of routine cerebral monitoring did not reveal any preexisting abnormality of the vertebral artery.

Teaching NeuroImages: Multicompartmental intracranial hemorrhage in a pediatric patient
A previously healthy 9-year-old girl presented with sudden-onset headache followed by confusion. In the emergency department, she was hypertensive, bradycardic, and no longer responsive to any stimuli. An emergent head CT scan demonstrated a left frontal intraparenchymal hematoma with intraventricular and subarachnoid extension as well as subfalcine herniation (figure). She underwent decompressive hemicraniectomy, and digital subtraction angiography confirmed a 7-mm left middle cerebral artery aneurysm (figure).

Three-dimensional modeling of Eagle syndrome
A 63-year-old man presented with transient episodes of left-hand weakness and right-eye vision loss following a lengthy airplane trip. The patient had reported right neck pain after sleeping awkwardly on the flight. Carotid dissection, paradoxical embolism, atherosclerotic occlusion, and thrombotic occlusion were considered possible etiologies of the associated carotid occlusion. Following a period of anticoagulation, a subsequent CT angiography (figure 1, A–C) revealed findings consistent with the styloid-carotid artery, or Eagle, syndrome.1 A 3-dimensional model was subsequently created (figure 2, A and B) utilizin...
