De Novo Renal Artery Stenosis Developed in Initially Normal Renal Arteries during the Long-Term Follow-Up of Patients with Moyamoya Disease

Moyamoya disease is a cerebrovascular disease of unknown origin causing progressive stenosis of the intracranial arteries in the circle of Willis.1,2 Stenoocclusive lesions and the subsequent hemodynamic compromise result in the formation of dilated, fragile collateral vessels at the base of the brain, which are termed moyamoya vessels. The presentation of patients with these lesions varies from asymptomatic to symptoms of headache, epilepsy, and ischemic and hemorrhagic stroke. Patients with moyamoya disease sometimes have concomitant extracranial arterial stenosis3; of all the extracranial arteries reported, the most common location of extracranial stenosis is the renal artery.

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...

Authors: Zhang H, Zheng L, Feng L Abstract Moyamoya disease (MMD) is a type of chronic cerebrovascular occlusion disease, which frequently occurs in East Asian populations, including pediatric and adult patients, and may lead to ischemic or hemorrhagic stroke, headache, epilepsy or transient ischemic attack. To date, the underlying mechanisms of MMD have remained to be fully elucidated, but certain studies have indicated that genetic factors may be an important component of its development. Cerebral angiography is the best approach for diagnosing MMD. However, with technological advances, non-invasive techniques ar...

ConclusionsThis analysis of nationally representative US data suggests that although readmission after RS for MMD is not uncommon, cerebral hemorrhagic events during the 90-day postoperative period are rare.

AbstractIn the province of Ferrara, Italy, the urgent neurological consultation (UNC) cases in the population correspond to the resident outpatients who undergo a UNC in the ER of the university hospital of Ferrara (UHFe). Thanks to this health organization a retrospective survey identified 612 UNC cases (range of age 7 –102 years, median 67,5 years) in the study period giving a period prevalence rate of 173 per 100,000 (95% CI 159.3–187.3) which increased with age (χ2 for trend  = 178.4p   0.70). The prevalence rate decreased with the distance between the patients&rsqu...

Abstract PURPOSE OF REVIEW: Spreading depression (SD) is a wave of simultaneous and near-complete depolarization of virtually all cells in brain tissue associated with a transient "depression" of all spontaneous or evoked electrical activity in the brain. SD is widely accepted as the pathophysiological event underlying migraine aura and may play a role in headache pathogenesis in secondary headache disorders such as ischemic stroke, subarachnoid or intracerebral hemorrhage, traumatic brain injury, and epilepsy. Here, we provide an overview of the pathogenic mechanisms and propose plausible hypotheses on ...

Answers (1) False, (2) False, (3) True, (4) False, (5) True, (6) False, (7) True, (8) True. This patient has an acute, non-haemorrhagic right middle cerebral territory infarct. There was involvement of the right precentral and postcentral gyri (motor and sensory areas) on other images. The axial T2-weighted image (figure 1) demonstrates high signal in swollen/oedematous ischaemic cortex with effacement of the sulci. There is also restricted diffusion in the affected area, with corresponding high/increased signal (bright) on DWI (figure 2), and low signal (dark) on the apparent diffusion coefficient (ADC) map (figure 3). In...
