Contrast-Enhanced High-Resolution MRI for Evaluating Time Course Changes in Middle Cerebral Artery Plaques.

CONCLUSION: Gadolinium contrast enhancement was found to be useful for effective evaluation of time course changes in the stability of symptomatic MCA stenotic plaques. PMID: 29540643 [PubMed - in process]

Posterior reversible encephalopathy syndrome (PRES) and reversible cerebral vasoconstriction syndrome (RCVS) are relatively uncommon neurological disorders, but their detection has been increasing mainly due to clinical awareness and spreading of magnetic resonance imaging (MRI). Because these syndromes share some common clinical and radiologic features and occasionally occur in the same patient, misdiagnosis may occur. PRES is characterized by varied neurological symptoms including headache, impaired visual acuity or visual field deficit, confusion, disorders of consciousness, seizures, and motor deficits often associated...

Authors: Rossi UG, Ierardi AM, Cariati M Abstract A 77-year-old woman with a history of hypertension developed acute onset of aphasia and right hemiplegia and hemisensory loss. She was urgently referred to emergency department. Cerebral multidetector computed tomographic angiography (MD-CTA) revealed an acute ischemic stroke due to the occlusion of the left middle cerebral artery (Figure 1). Since the symptoms started three hours previously, the patient was candidate for mechanical thrombectomy. The patient then performed a selective digital subtraction angiography (DSA) of the left internal carotid artery that con...

This study assessed the safety and usefulness of pretreatment using a high-dose strong statin (HDSS) to reduce the periprocedural ischemic complications of CAS. We analyzed 117 carotid lesions treated by CAS that were evaluated with magnetic resonance imaging (MRI) within 48  h after the procedure. For 67 lesions, an HDSS (rosuvastatin 20 mg or atorvastatin 40 mg daily) were prescribed from at least 14 days before CAS to at least 14 days after procedure (HDSS group). Clinical and angiographic data, as well as in-hospital outcomes, of the HDSS group were retrospecti vely compared with 50 lesions wit...

We report the case of a 14-year-old girl who presented with right-sided weakness and ataxia, loss of sensation, and altered mental status. Magnetic resonance imaging with diffusion-weighted imaging showed an acute lesion in the distribution of the left posterior cerebral artery, and magnetic resonance angiogram demonstrated occlusion of the third branch of the left posterior cerebral artery. With parental consent, clinicians decided to infuse an adult dose of weight-adjusted intravenous alteplase at 3.5 hours from onset of symptoms, with subsequent improvement in National Institutes of Health Stroke Scale score from 11 to ...

UP TO 40% of all ischemic strokes are considered cryptogenic, implying a stroke without a definitive etiology.1,2 With a dearth of evidence-guided treatment strategies, the literature surrounding cryptogenic stroke is highly variable and not well-standardized. Even though existing guidelines do not specify the exact testing required, the cryptogenic stroke evaluation includes a variety of imaging modalities (eg, echocardiography, angiography, magnetic resonance imaging, carotid ultrasound) and laboratory investigations (eg, genetic testing, hypercoagulable disorder panels, erythrocyte sedimentation rate).

We report a case of moyamoya disease with epileptic nystagmus. A 23-year-old woman presented with a headache and transient hemiparesis on her left side. Magnetic resonance imaging showed no ischemic or hemorrhagic stroke lesions. Digital subtraction angiography confirmed stenosis of the terminal portion of the right internal carotid artery and the formation of moyamoya vessels on the right side. 123I-N-isopropyl-iodoamphetamine (123I-IMP) single photon emission computed tomography (SPECT) showed decreased uptake in the right basal ganglia, frontal, and parietal regions. After electroencephalography (EEG) and a hyperventila...

This study aimed to report a Chinese patient with acute bilateral pontine infarction manifesting as eight-and-a-half syndrome plus hemiplegia (atypical nine syndrome), and also the clinical and neuroimaging findings were explained and discussed with review of the literature. Patient concerns: A 79-year-old woman experienced sudden vertigo, nausea, vomiting, and weakness at her left arm and leg. The neurological examination disclosed her right horizontal gaze palsy, internuclear ophtalmoplegia (INO), and right-sided peripheral facial paralysis combined with slight left-sided hemiplegia, which were consistent with atypica...
