Case Report: Vertebral Artery Dissection After Intravascular Stenting of the Contralateral Unruptured Vertebral Artery Aneurysm.

Front Neurol 2021 23;12:599197. Epub 2021 Apr 23.

Department of Interventional Neuroradiology, Beijing Neurosurgical Institute, Beijing Tian Tan Hospital, Capital Medical University, Beijing, China.

Spontaneous vertebral artery dissecting aneurysm has been increasingly attributed as a major cause of focal neurological deficits due to vertebrobasilar artery ischemia or subarachnoid hemorrhage (SAH). Although the development of spontaneous vertebral artery dissecting aneurysm (VADA) is rare, VADA after treatment of contralateral vertebral artery (VA) is more less frequently observed. There are only a few reports related to VADA after treatment of the contralateral VA in the medical literature. Read More

Combined Endovascular and Microsurgical Management of a Tentorial Arteriovenous Malformation in a Hybrid Neurovascular Operating Room: 2-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2021 May 6. Epub 2021 May 6.

Department of Neurosurgery, University of Pennsylvania, Philadelphia, Pennsylvania, USA.

Tentorial margin arteriovenous malformations (AVMs) at the cerebello-mesencephalic fissure are deep lesions, which can be safely resected via a lateral supracerebellar infratentorial approach. This video illustrates the case of a patient who presented with hemorrhage from a tentorial AVM. He was managed in the hybrid neurovascular operating room with Onyx (Medtronic) embolization of a superior cerebellar artery feeder followed by resection of the AVM, which included cerebellar relaxation from lumbar cerebrospinal fluid (CSF) drainage and lateral positioning.

Cerebellar developmental venous anomaly with associated cavernoma causing a hemorrhage - a rare occurrence.

Radiol Case Rep 2021 Jun 13;16(6):1463-1468. Epub 2021 Apr 13.

Department of Radiology, Southend University Hospital NHS Foundation Trust, Southend-on-Sea, UK.

Developmental venous anomalies (DVAs) are variations in the transmedullary veins required for drainage of the brain. Normally, when occurring in isolation, DVAs are not clinically significant and are therefore usually a benign diagnosis. Thus, they are most often an incidental finding unless associated with an adjacent pathology. Read More

Zh Nevrol Psikhiatr Im S S Korsakova 2021 ;121(3. Vyp. 2):46-52

Privolzhsky Research Medical University, Nizhny Novgorod, Russia.

Cerebral amyloid angiopathy (CAA) is caused by the deposition of β-amyloid in small vessels in the cerebral cortex and leptomeninges. Nowadays, CAA is recognized more often due to the development of neuroimaging technologies. The frequency of CAA increases in old age that explains its frequent association with cardiovascular diseases. Read More

Birth-related subdural hemorrhage: prevalence and imaging morphology.

Pediatr Radiol 2021 04 8. Epub 2021 Apr 8.

Department of Radiology, University of Arkansas for Medical Sciences (UAMS), Little Rock, AR, USA.

Background: Birth trauma accounts for 1-2% of the mortality in newborns with significant intracranial injuries presenting in the immediate postnatal period. However, a significant number of asymptomatic neonates harbor birth-related intracranial hemorrhage (ICH), with birth-related subdural hemorrhage (SDH) being a common occurrence on infant brain CT and MRI studies performed as a standard of care for a variety of reasons. Although clinically insignificant, birth-related SDH is frequently brought up in courts as an alternative explanation for SDH in suspected abusive head trauma. Read More

Damage to the central nucleus of the thalamus via atypical Holmes tremor: a case report.

J Int Med Res 2021 Apr;49(4):300060521999567

Hospital of Chengdu University of Traditional Chinese Medicine, Chengdu, Sichuan Province, PR China.

Holmes tremor (HT) is a rare symptomatic movement disorder characterized by a combination of resting, postural, and action tremors. HT is usually caused by lesions in the brain stem, thalamus, and cerebellum, and the pathogenesis is believed to be related to the nigrostriatal pathway and/or the cerebello-thalamo-cortical pathway. Many medications have been used to treat HT with various degrees of effectiveness. Read More

Biochem Biophys Res Commun 2021 May 1;555:89-94. Epub 2021 Apr 1.

Division of Cardiovascular Sciences, School of Medical Sciences, Faculty of Biology, Medicine and Health, The University of Manchester, Manchester, M13 9WL, UK; Centre for Advanced Discovery and Experimental Therapeutics (CADET), Manchester Academic Health Sciences Centre, Manchester, UK; School of Biological Sciences, Faculty of Science, University of Auckland, Private Bag 92 019, Auckland, 1142, New Zealand. Electronic address:

Sporadic Alzheimer's disease (sAD) is the commonest cause of age-related neurodegeneration but there are no available treatments with demonstrated disease-modifying actions. It is therefore relevant to study hitherto-unknown aspects of brain structure and function to seek new disease-related mechanisms that might be targeted by novel disease-modifying interventions. During hypothesis-generating proteomic investigations in a case-control study of sAD, we observed widespread elevations of haptoglobin and haemopexin in all six brain-regions studied, which together represent much of the brain.

Background The third trimester of gestation is a crucial phase of rapid brain development, but little has been reported on the trajectories of cerebral blood flow (CBF) in preterm infants in this period. Purpose To quantify regional CBF in very preterm infants longitudinally across the ex utero third trimester and to determine its relationship with clinical factors associated with brain injury and premature birth. Materials and Methods In this prospective study, very preterm infants were enrolled for three longitudinal MRI scans, and 22 healthy full-term infants were enrolled for one term MRI scan between November 2016 and February 2019.

Consensus Approach for Standardizing the Screening and Classification of Preterm Brain Injury Diagnosed With Cranial Ultrasound: A Canadian Perspective.

Front Pediatr 2021 8;9:618236. Epub 2021 Mar 8.

Department of Pediatrics, Mount Sinai hospital, Toronto, ON, Canada.

Acquired brain injury remains common in very preterm infants and is associated with significant risks for short- and long-term morbidities. Cranial ultrasound has been widely adopted as the first-line neuroimaging modality to study the neonatal brain. It can reliably detect clinically significant abnormalities that include germinal matrix and intraventricular hemorrhage, periventricular hemorrhagic infarction, post-hemorrhagic ventricular dilatation, cerebellar hemorrhage, and white matter injury.

[Dural Arteriovenous Fistula].

No Shinkei Geka 2021 Mar;49(2):362-367

Department of Radiology, Faculty of Medicine, Oita University.

Dural arteriovenous fistulas(dAVFs), which are arteriovenous shunts between the dural/epidural artery and dural vein and/or dural venous sinus, can cause various symptoms, and the risk of aggressive symptoms such as cerebral hemorrhage and venous infarction mainly depends on venous drainage patterns in patients. Patients with dAVFs with cortical venous reflux have a high risk of aggressive symptoms due to cerebral venous congestion or varix rupture, and they often develop brain edema and/or hemorrhage. In some cases, patients with dAVFs may have CT and MRI findings similar to those of patients with brain tumors. Read More
