Stroke Mimics in the Acute Setting: Role of Multimodal CT Protocol ADULT BRAIN
CONCLUSIONS: Multimodal CT demonstrated low sensitivity but high specificity in the diagnosis of stroke mimics in the acute setting. The high specificity of multimodal CT allows ruling out stroke and thereby avoiding unnecessary revascularization treatment in patients with diagnosis of a stroke mimic.

Magnetic resonance imaging of arterial stroke mimics: a pictorial review
AbstractAcute ischaemic stroke represents the most common cause of new sudden neurological deficit, but other diseases mimicking stroke happen in about one-third of the cases. Magnetic resonance imaging (MRI) is the best technique to identify those ‘stroke mimics’. In this article, we propose a diagnostic approach of those stroke mimics on MRI according to an algorithm based on diffusion-weighted imaging (DWI), which can be abnormal or normal, followed by the results of other common additional MRI sequences, such as T2 with gradient recall ed echo weighted imaging (T2-GRE) and fluid-attenuated inversion recovery (FLAIR...

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...

Stroke in children and adolescents.
Abstract The occurrence of a stroke in children and adolescents constitutes a rare, critical event that is associated with substantial morbidity and mortality. In addition to the individual suffering for the young patient and the medical burden for the affected family, a stroke is also associated with high follow-up costs for the health system because of the necessary long-term rehabilitative treatment. Establishing an early and prompt diagnosis is of great therapeutic importance. Because of the rarity of the illness and the plethora of clinical manifestations, diagnosis is often delayed. The most frequent clini...

MR screening of candidates for thrombolysis: How to identify stroke mimics?
Publication date: December 2014 Source:Journal of Neuroradiology, Volume 41, Issue 5 Author(s): F. Danière , M. Edjlali-Goujon , C. Mellerio , G. Turc , O. Naggara , L. Tselikas , W. Ben Hassen , M. Tisserand , C. Lamy , R. Souillard-Scemama , S. Flais , J.F. Meder , C. Oppenheim Stroke mimics account for up to a third of suspected strokes. The main causes are epileptic deficit, migraine aura, hypoglycemia, and functional disorders. Accurate recognition of stroke mimics is important for adequate identification of candidates for thrombolysis. This decreases the number of unnecessary treatments and invasive vascular inves...

Stroke-Like Migraine Attacks after Radiation Therapy (SMART) Syndrome Is Not Always Completely Reversible: A Case Series FELLOWS' JOURNAL CLUB
SUMMARY: We retrospectively reviewed clinical and imaging findings in 11 patients with stroke-like migraine attacks after radiation therapy (SMART) syndrome to better understand this disorder previously thought to be reversible. Six men and 5 women had complex bouts of neurologic impairment beginning, on average, 20 years after cerebral irradiation. All had characteristic, unilateral gyriform enhancement on MR imaging that developed within 2–7 days and typically resolved in 2–5 weeks. Unlike prior reports, 45% had incomplete neurologic recovery manifesting as dysphasia, cognitive impairment, or hemiparesis. The...

Susceptibility-weighted imaging in stroke-like migraine attacks after radiation therapy syndrome
Conclusion These preliminary findings suggest that SWI may help identify SMART syndrome or at least help discriminate it from other disorders, by the findings of numerous susceptibility hypointensities on SWI likely representing RICHs, gyriform enhancement on T1WI, and postsurgical findings or appropriate clinical history.

Time Course of Cerebral Perfusion Changes in Children with Migraine with Aura Mimicking Stroke PEDIATRICS
We present 12 pediatric patients with acute hemiplegic migraine or migraine with aura who underwent MR imaging within 12 hours of symptom onset. Quantitative and qualitative analyses were performed on arterial spin-labeling; and qualitative analysis, on SWI and MRA sequences. All 12 patients had normal DWI and abnormal arterial spin-labeling findings. Furthermore, we observed a more rapid transition from hypoperfusion to rebound hyperperfusion in 3 patients compared with prior reports. These findings support the use of multimodal MR imaging to distinguish migraine with aura from stroke and the simultaneous use of these MR ...

Atypical imaging findings of presumed stroke-like migraine attacks after radiation therapy syndrome in the brainstem
AbstractThe authors present an atypical case of presumed stroke-like migraine attacks after radiation therapy (SMART) syndrome in the brainstem. A 29-year-old male, who had been treated with resection and subsequent craniospinal radiation for posterior fossa medulloblastoma 21 years before, presented with subacute progressive left hemiparesis evolving over 4 days. Hematological findings, cerebrospinal fluid (CSF), and electroencephalogram (EEG) were unremarkable. Magnetic resonance imaging (MRI) showed a round area of hyperintense FLAIR signal centered within the pons associated with central restricted diffusion, periphera...

Prognostic Factors of Stroke-Like Migraine Attacks after Radiation Therapy (SMART) Syndrome ADULT BRAIN
CONCLUSIONS: Age, use of steroid treatment at the diagnosis of SMART syndrome, and MR imaging findings of abnormal susceptibility signal, restricted diffusion, and subcortical WM change in the acute SMART region can be prognostic factors in SMART syndrome.

Severe symptomatic intracranial internal carotid artery stenosis treated with intracranial stenting: a single center study with 58 patients.
CONCLUSION: Intracranial stenting for patients with intracranial ICA atherosclerotic stenosis has a low perioperative stroke rate and decent outcome on long-term follow-up, despite a relatively high in-stent restenosis rate. PMID: 26809831 [PubMed - as supplied by publisher]

ACR Appropriateness Criteria ® Cerebrovascular Disease-Child
Stroke is an uncommon but an important and under-recognized cause of morbidity and mortality in children. Strokes may be due to either brain ischemia or intracranial hemorrhage. Common symptoms of pediatric acute stroke include headache, vomiting, focal weakness, numbness, visual disturbance, seizures, and altered consciousness. Most children presenting with an acute neurologic deficit do not have an acute stroke, but have symptoms due to stroke mimics which include complicated migraine, seizures with postictal paralysis, and Bell palsy.
