Teaching NeuroImages: Eagle syndrome: Cerebrovascular complications
A 70-year-old man developed acute onset of aphasia and right-sided hemiplegia in the setting of mild hypotension after hemodialysis. Brain MRI (figure, D and E) revealed diffusion restriction in the left anterior and middle cerebral artery territories. Brain CT (figure, A–C) was significant for an elongated styloid process causing mild compression of the left internal carotid artery. A comprehensive workup for stroke etiology was otherwise unremarkable.

Teaching Video NeuroImages: Movement of a paralyzed arm with yawning
A 63-year-old man presented with aphasia and right arm paralysis (Medical Research Council [MRC] grade 0), sparing the leg (video 1 on the Neurology® Web site at Neurology.org). With yawning, his right arm consistently rose to his chest (video 2). Paralysis resumed after yawning. MRI confirmed an acute ischemic stroke in the left middle cerebral artery distribution (figure). This movement ceased after 2 weeks following partial recovery of arm strength (MRC grade 4). This phenomenon, first described in the 1844, was recently coined parakinesia brachialis oscitans. It is speculated to be a release event in which damaged ...

Differences in Ischaemic and Haemorrhagic Strokes in Sri Lanka: 7-year data from the Ragama Stroke Registry (P1.092)
CONCLUSIONS:Clinical and risk factor profiles were different between ICH and IS patients. Stroke severity and functional disability were higher among ICH patients. Study Supported by:Ragama Stroke Registry has been partly supported by research grants from the University of Kelaniya and Research Institute, International Medical Centre of Japan.Disclosure: Dr. Ranawaka has nothing to disclose.

Short-Term Functional Outcome and its Predictors in a Hospital-Based Cohort of Nigerians with Acute Stroke (P5.171)
CONCLUSIONS: About 1 in 3 stroke patients in this cohort had poor functional outcome. In order to improve functional outcome and reduce the burden of stroke in Nigeria, public health education on early recognition and hospital presentation is needed. In acute stroke management, complications should be prevented while speech and language therapy should be instituted to improve functional outcome.Disclosure: Dr. Wahab has nothing to disclose.

Teaching NeuroImages: Radiation-associated symptomatic carotid artery disease with ipsilateral radiodermatitis
A 68-year-old man with a history of squamous cell carcinoma of the tongue treated with external beam radiation therapy in 2007 presented in 2013 with acute onset expressive aphasia and right lower facial weakness. MRI confirmed an acute infarct in the left frontal cortex. CT angiography revealed occlusion vs critical stenosis of the left internal carotid artery, new from 2007. Examination of the patient's neck revealed ipsilateral radiodermatitis (figure). Therapeutic neck irradiation has been associated with accelerated atheromatous disease, carotid artery stenosis, and increased risk of stroke.1,2 Ipsilateral radiodermat...

Teaching NeuroImages: Macaroni sign
A 35-year-old patient with previously diagnosed and currently untreated Takayasu arteritis presented with motor aphasia. The symptom had started 24 hours before presentation and ceased after another 12 hours. Cranial MRI and magnetic resonance angiography were normal. Plasma concentration of C-reactive protein was elevated (9.1 mg/dL). Duplex ultrasonography showed hypoechoic, homogeneous thickening of the intima–media complex of the left common carotid artery (figure). This finding, also referred to as "macaroni sign," has been reported in Takayasu arteritis.1,2 The patient was transferred to the rheumatologic depar...

Teaching NeuroImages: Susceptibility-weighted MRI: First clue to DAVF complicating sinovenous thrombosis
A 61-year-old man with factor V Leiden thrombophilia presented with hemorrhage and transverse sinus thrombosis (figure, A). Four years later, he developed worsening aphasia, new hemorrhage, and hemispheric edema (figure, B). Susceptibility-weighted imaging (SWI) showed bright signal in the straight sinus (figure, C). A dural arteriovenous fistula (DAVF) was diagnosed (figure, D). The brain edema improved (figure, E) and SWI sinus hyperintensity resolved after endovascular disconnection of the fistula (figure, F).

Teaching NeuroImages: Treatment-resistant rapidly progressive amyloid {beta}-related angiitis
A 76-year-old woman presented with 1 month of progressive aphasia, headache, and subsequent right hemiparesis. Initial brain MRI showed a punctate infarct (figure 1, A and C). Susceptibility-weighted imaging was unremarkable. A repeat study 16 days later demonstrated bihemispheric infarcts with multifocal attenuation of intracranial vessels on magnetic resonance angiography (figure 1, B and D). CSF showed a lymphocytic pleocytosis (101 leukocytes/µL) and elevated protein (480 mg/dL). Brain biopsy showed granulomatous angiitis with amyloid deposition and fibrinoid necrosis surrounded by inflammatory cells (figure 2). ...
