Crossed Cerebellar Tracer Uptake on Acute-Stage 123I-Iomazenil SPECT Imaging Predicts 3-Month Functional Outcome in Patients With Nonfatal Hypertensive Putaminal or Thalamic Hemorrhage.

Clin Nucl Med 2018 Jun;43(6):396-401

From the Department of Neurosurgery and Cyclotron Research Center, Iwate Medical University, Morioka, Japan.

Purpose: Whereas SPECT images obtained 180 minutes after administration of I-iomazenil (IMZ) (late images) are proportional to the distribution of central benzodiazepine receptor-binding potential, SPECT images obtained within 30 minutes after I-IMZ administration (early images) correlate with regional brain perfusion. The aim of the present study was to determine whether crossed cerebellar tracer uptake on acute-stage I-IMZ SPECT imaging predicts 3-month functional outcome in patients with nonfatal hypertensive putaminal or thalamic hemorrhage.

Methods: Forty-six patients underwent early and late SPECT imaging with I-IMZ within 7 days after the onset of hemorrhage. Read More

'Khatatonia' - cathinone-induced hypertensive encephalopathy.

Neth J Med 2017 Dec;75(10):448-450

Quantitative Neuroimaging Group, Academic Unit of Neurology, Trinity College Dublin, Ireland.

Khat consumption is an under-recognised cause of hypertensive encephalopathy and intraparenchymal brain haemorrhage. We report the radiological findings of extensive periventricular, subcortical and brain stem white matter pathology of a patient who had consumed excessive amounts of Khat. The Khat plant contains cathinone, an amphetamine-like alkaloid which has been associated with chronic hypertensive end-organ damage, but is seldom considered a cause of cerebrovascular events in northern Europe.

Neuroimaging Correlates of Cerebral Microbleeds: The ARIC Study (Atherosclerosis Risk in Communities).

Stroke 2017 11 10;48(11):2964-2972. Epub 2017 Oct 10.

From the Departments of Neurology (J.G.R., D.S.K.) and Radiology (K.K., C.R.J., P.V.), Mayo Clinic, Rochester, MN; Department of Data Science, Gertrude Ford MIND Center (J.S., M.E.G.) and Department of Medicine (T.H.M., B.G.W.), University of Mississippi Medical Center, Jackson; Department of Neurology (M.S.A., R.F.G.), Johns Hopkins University, Baltimore, MD; and Department of Epidemiology (A.R.S., R.F.G.), Johns Hopkins Bloomberg School of Public Health, Baltimore, MD.

Background And Purpose: Cerebral microbleed (CMB) location (deep versus strictly lobar) may elucidate underlying pathology with deep CMBs being more associated with hypertensive vascular disease and lobar CMBs being more associated with cerebral amyloid angiopathy. The objective of this study was to determine whether neuroimaging signs of vascular disease and Alzheimer pathology are associated with different types of CMBs.

Methods: Among 1677 nondemented ARIC (Atherosclerosis Risk in Communities) participants (mean age=76±5 years; 40% men; 26% black) with 3-Tesla MRI scans at the fifth examination (2011-2013), we fit multinomial logistic regression models to quantify relationships of brain volumes (Alzheimer disease signature regions, total gray matter, frontal gray matter, and white matter hyperintensity volumes), infarct frequencies (lacunar, nonlacunar, and total), and apolipoprotein E (number of ε4 alleles) with CMB location (none, deep/mixed, or strictly lobar CMBs).

Ascertaining the Value of Noninvasive Measures Obtained Using Color Duplex Ultrasound and Central Aortic Pressure Monitoring During the Management of Cerebral Arteriovenous Malformation Resection: Protocol for a Prospective, Case Control Pilot Study.

JMIR Res Protoc 2017 Aug 31;6(8):e173. Epub 2017 Aug 31.

Faculty of Medicine and Health Sciences, Macquarie University, Sydney, Australia.

Background: Dramatic hemodynamic changes occur upon removal of an arteriovenous malformation of the brain (bAVM) with a number of potentially serious perioperative complications, such as intracranial hemorrhage and venous occlusive hypertensive syndrome. As these complications largely occur in the postoperative inpatient period, a rapid, repeatable noninvasive investigation to serially monitor relevant intracranial hemodynamics may be of benefit. Though, transcranial Doppler (TCD) and transcranial color duplex (TCCD) are techniques used and available to provide hemodynamic measurements postoperatively, the time course of hemodynamic sequences following bAVM resection remains uncertain.

Risk factors are different for deep and lobar remote hemorrhages after intravenous thrombolysis.

PLoS One 2017 22;12(6):e0178284. Epub 2017 Jun 22.

Servei de neuorlogia, Hospital de la Santa Creu i Sant Pau (Biomedical Research Institute, IIB-Sant Pau), Barcelona, Spain.

Background And Purpose: Remote parenchymal haemorrhage (rPH) after intravenous thrombolysis is defined as hemorrhages that appear in brain regions without visible ischemic damage, remote from the area of ischemia causing the initial stroke symptom. The pathophysiology of rPH is not clear and may be explained by different underlying mechanisms. We hypothesized that rPH may have different risk factors according to the bleeding location.

Amyloid positron emission tomography in sporadic cerebral amyloid angiopathy: A systematic critical update.

Neuroimage Clin 2017 5;15:247-263. Epub 2017 May 5.

U894, Centre Hospitalier Sainte Anne, Sorbonne Paris Cité, Paris, France. Electronic address:

Sporadic cerebral amyloid angiopathy (CAA) is a very common small vessel disease of the brain, showing preferential and progressive amyloid-βdeposition in the wall of small arterioles and capillaries of the leptomeninges and cerebral cortex. CAA now encompasses not only a specific cerebrovascular pathological trait, but also different clinical syndromes - including spontaneous lobar intracerebral haemorrhage (ICH), dementia and 'amyloid spells' - an expanding spectrum of brain parenchymal MRI lesions and a set of diagnostic criteria - the Boston criteria, which have resulted in increasingly detecting CAA during life. Although currently available validated diagnostic criteria perform well in multiple lobar ICH, a formal diagnosis is currently lacking unless a brain biopsy is performed. Read More

Cerebral microbleeds and risk of incident dementia: the Framingham Heart Study.

Neurobiol Aging 2017 06 6;54:94-99. Epub 2017 Mar 6.

Department of Neurology, School of Public Health at Boston University, Boston, MA, USA; NHLBI's Framingham Heart Study, Framingham, MA, USA.

Cerebral microbleeds (CMBs) are MRI markers attributed to the most common cerebral angiopathies in the elderly and in patients with dementia: hypertensive and cerebral amyloid angiopathy. CMB detection in asymptomatic persons may help identify those at risk for dementia and may influence preventive strategies and design of clinical trials testing treatments for dementia. We studied the association of CMB with risk of incident dementia in community dwelling individuals. Read More
