Anesthesia Management for Pediatric Patient With Multiple Endocrine Neoplasia Type 2B: A Case Report.

A A Pract 2020 May;14(7):e01215

From the University of Oklahoma Health Sciences Center, Oklahoma City, Oklahoma.

Administering anesthesia to patients with pheochromocytoma may cause an exacerbation of catecholamine secretion from the pheochromocytoma secondary to drug administration, stress, or manipulation of the tumor. We present a pediatric patient with undiagnosed multiple endocrine neoplasia type 2B (pheochromocytoma, thyroid carcinoma, and mucosal neuromas), initially diagnosed and treated for postviral myocarditis and cardiomyopathy, who presented for abdominal magnetic resonance imaging (MRI) under general anesthesia. Untreated cardiomyopathy poses an extra anesthesia mortality risk for patients with pheochromocytoma usually due to myocardial failure, myocardial infarction, or hypertensive hemorrhage into the myocardium or brain.

Alina Uzelac

Radiol Clin North Am 2020 Jan 18;58(1):187-197. Epub 2019 Oct 18.

Neuroradiology, Department of Radiology, Zuckerberg San Francisco General Hospital, University of California, 1001 Potrero Avenue, Room 1X56, San Francisco, CA 94110, USA. Electronic address:

Neuroimaging is an invaluable diagnostic tool for sorting through the vast array of etiologies that underlie altered mental status (AMS). Head computed tomography (CT) without contrast is the primary modality for evaluation of AMS and should be complemented by MR imaging in cases of negative CT but high clinical concern. Studies to maximize brain imaging efficiency and improve the yield of positive scans through the utilization of clinical and laboratory pre-scan diagnostics are ongoing. Read More

Superficial Cerebellar Microbleeds and Cerebral Amyloid Angiopathy: A Magnetic Resonance Imaging/Positron Emission Tomography Study.

Stroke 2020 01 15;51(1):202-208. Epub 2019 Nov 15.

Departments of Neurology (H.-H.T., L.-K.T., Y.-W.C., S.-C.T., J.-S.J.), National Taiwan University Hospital, Taipei.

Background and Purpose- The differentiation between cerebral amyloid angiopathy (CAA) and hypertensive small vessel disease in primary intracerebral hemorrhage is mainly based on hemorrhagic neuroimaging markers in the supratentorial regions, and the cause for cerebellar microbleeds remains unknown. Our aim was to investigate whether superficial cerebellar microbleeds are more likely to be related to CAA rather than hypertensive small vessel disease. Methods- Two hundred seventy-five consecutive patients with intracerebral hemorrhage were retrospectively reviewed from a prospectively maintained hospital-based stroke registry. Read More

Underlying Small Vessel Disease Associated With Mixed Cerebral Microbleeds.

Front Neurol 2019 23;10:1126. Epub 2019 Oct 23.

Neurology Department, Hôpital Pierre-Paul Riquet, Centre Hospitalier Universitaire de Toulouse, Toulouse, France.

Whether patients with both lobar and deep cerebral microbleeds (mixed CMB) have advanced cerebral amyloid angiopathy (CAA), hypertensive angiopathy (HA) or both is uncertain. To get insight into the underlying small vessel disease (SVD) associated with mixed CMB, we explored its association with cortical superficial siderosis (cSS), a key marker of CAA and other MRI markers of SVD in patients with intracerebral hemorrhage (ICH). Of 425 consecutive patients with acute ICH who had received brain MRIs, 260 had ≥1 CMB and were included in the analysis. Read More

Invited Review: The spectrum of age-related small vessel diseases: potential overlap and interactions of amyloid and nonamyloid vasculopathies.

Neuropathol Appl Neurobiol 2020 Apr 11;46(3):219-239. Epub 2019 Sep 11.

Stroke Research Centre, Department of Brain Repair & Rehabilitation, UCL Institute of Neurology, The National Hospital for Neurology and Neurosurgery, London, UK.

Deep perforator arteriopathy (DPA) and cerebral amyloid angiopathy (CAA) are the commonest known cerebral small vessel diseases (CSVD), which cause ischaemic stroke, intracebral haemorrhage (ICH) and vascular cognitive impairment (VCI). While thus far mainly considered as separate entities, we here propose that DPA and CAA share similarities, overlap and interact, so that 'pure' DPA or CAA are extremes along a continuum of age-related small vessel pathologies. We suggest blood-brain barrier (BBB) breakdown, endothelial damage and impaired perivascular β-amyloid (Aβ) drainage are hallmark common mechanisms connecting DPA and CAA. Read More

Enlarged perivascular spaces and florbetapir uptake in patients with intracerebral hemorrhage.

Eur J Nucl Med Mol Imaging 2019 Oct 29;46(11):2339-2347. Epub 2019 Jul 29.

Department of Neurology, Hôpital Pierre-Paul Riquet, Centre Hospitalier Universitaire de Toulouse, Place Baylac, 31059, Toulouse Cedex 9, France.

Purpose: Enlarged perivascular spaces in the centrum semiovale (CSO-EPVS) have been linked to cerebral amyloid angiopathy (CAA). To get insight into the underlying mechanisms of this association, we investigated the relationship between amyloid-β deposition assessed by 18F-florbetapir PET and CSO-EPVS in patients with acute intracerebral hemorrhage (ICH).

Methods: We prospectively enrolled 18 patients with lobar ICH (suggesting CAA) and 20 with deep ICH (suggesting hypertensive angiopathy), who underwent brain MRI and 18F-florbetapir PET. Read More

[SPONTANEOUS PARENCHYMAL INTRACRANIAL HEMORRHAGE - A DIAGNOSTIC CHALLENGE].

Harefuah 2018 03;157(3):158-161

Department of Neurology, Hadassah Medical Center, Jerusalem Israel.

Introduction: Non-traumatic intracranial hemorrhage (ICH) is a devastating event associated with a high rate of morbidity and mortality. Patient age, hemorrhage location, number of foci, and underlying diseases are important clues to the etiology. Non-contrast head CT, given its availability and high sensitivity in detecting blood products, is frequently the first tool to readily detect ICH; however, different types of hemorrhages may share a common appearance on CT and the optimal therapeutic approach varies depending on etiology.

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.

Background and distribution of lobar microbleeds in cognitive dysfunction.

Brain Behav 2017 11 16;7(11):e00856. Epub 2017 Oct 16.

Department of Neurology Mie University Graduate School of Medicine Tsu Mie Japan.

Objectives: Cerebral microbleeds (CMBs) are often observed in memory clinic patients. It has been generally accepted that deep CMBs (D-CMBs) result from hypertensive vasculopathy (HV), whereas strictly lobar CMBs (SL-CMBs) result from cerebral amyloid angiopathy (CAA) which frequently coexists with Alzheimer's disease (AD). Mixed CMBs (M-CMBs) have been partially attributed to HV and also partially attributed to CAA. Read More

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.
