Hemodynamic alterations following a cerebellar arteriovenous malformation resection: Case report and densitometric quantitative analysis from CT imaging.

Neurocirugia (Astur : Engl Ed) 2022 May-Jun;33(3):141-148

Department of Neurosurgery, University Hospital 12 de Octubre, Avda de Córdoba s/n, Madrid 28041, Spain.

Background: Cerebellar arteriovenous malformations (cAVMs) are rare and challenging lesions with an aggressive natural history. The mechanisms whereby a patient can worsen clinically after a supratentorial AVM resection include an acute alteration in cerebral hemodynamics, which is a known cause of postoperative hyperemia, edema and/or hemorrhage. These phenomena has not been described for cAVMS. Read More

R558C NOTCH3 Mutation in a CADASIL Patient with Intracerebral Hemorrhage: A Case Report with Literature Review.

J Stroke Cerebrovasc Dis 2022 Jul 3;31(7):106541. Epub 2022 May 3.

Department of Neurology, The First Affiliated Hospital, Sun Yat-Sen University, Guangzhou 510080, China. Electronic address:

Background: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a monogenic cerebral small-vessel disease, which is characterized by migraine, recurrent ischemic strokes, psychiatric disorder, progressive cognitive decline, and occasionally intracerebral hemorrhage (ICH). ICH events have been reported in a high proportion of East Asian CADASIL patients with R544C mutation in exon 11 of NOTCH3; however, whether any other specific NOTCH3 mutation determines the ICH phenotype has yet to be explored.

Case Presentation: We report the case of a 60-year-old male CADASIL patient with a novel R558C mutation in exon 11 of the NOTCH3 gene, who presented with ICH in the basal ganglia and cerebellum. Read More

Machine learning model prediction of 6-month functional outcome in elderly patients with intracerebral hemorrhage.

Neurosurg Rev 2022 May 6. Epub 2022 May 6.

Department of Neurosurgery, Fondazione Policlinico Universitario A. Gemelli IRCSS, Rome, Italy.

Spontaneous intracerebral hemorrhage (ICH) has an increasing incidence and a worse outcome in elderly patients. The ability to predict the functional outcome in these patients can be helpful in supporting treatment decisions and establishing prognostic expectations. We evaluated the performance of a machine learning (ML) model to predict the 6-month functional status in elderly patients with ICH leveraging the predictive value of the clinical characteristics at hospital admission.

Multimodality resection of Oliveira Type IIIC* cerebellar AVM: A distinct entity.

Surg Neurol Int 2022 22;13:163. Epub 2022 Apr 22.

Department of Neurosurgery, Harvard Medical School, Brigham and Women's Hospital, Boston, United States.

Background: Posterior fossa AVMs constitute about 10% of AVMs and are associated with a higher rate of hemorrhage and increased morbidity and mortality rates necessitating treatment with rare exception. Cerebellar AVMs differ markedly from their supratentorial counterparts in that there are no perforating vessels involvement, drainage into the deep cerebral venous system, or presence of eloquent functional area except for the dentate nucleus. While Yaşargil has classified cerebellar AVMs into seven subtypes according to their location, de Oliveira . Read More

Department of Forensic Medicine, Tongji Medical College, Huazhong University of Science and Technology, No. 13 Hangkong Road, Wuhan, 430030, People's Republic of China.

Allan-Herndon-Dudley syndrome (AHDS) is a very rare, X-linked psychomotor disability syndrome with delayed myelination, almost exclusively affecting boys. We present a case of a 4-year-old boy with AHDS who was found cyanotic, with intermittent vomiting and paroxysmal convulsions about 4 h after his parents went out, and was then taken to the hospital, where he eventually died the next day. The autopsy revealed foreign bodies in the tiny bronchi and alveoli of the deceased, congestion, and punctate hemorrhage in multiple organs, consistent with the diagnosis of asphyxia. Read More

Remote cerebellar hemorrhage after a neurosurgical procedure: A report of three cases.

J Cerebrovasc Endovasc Neurosurg 2022 Mar 24. Epub 2022 Mar 24.

Department of Neurosurgery, Seoul National University Hospital, Seoul, Korea.

Remote cerebellar hemorrhage (RCH) is a rare complication of neurosurgical procedures and is characterized by a typical bleeding pattern defined as the "zebra sign." Only few cases of RCH have been reported in the English literature, and its pathophysiology remains unclear. In this report, we present the cases of three patients with RCH after three different procedures: burr-hole trephination and chronic subdural hematoma evacuation of bilateral cerebral convexity with subsequent subdural drain insertion, lumbar drainage for cerebrospinal fluid divergence for thoracic endovascular aortic repair, and combined bypass surgery for moyamoya disease.

The Acute Superficial Siderosis Syndrome - Clinical Entity, Imaging Findings, and Histopathology.

Cerebellum 2022 Mar 22. Epub 2022 Mar 22.

Department of Neurology, University Hospital/Goethe University Frankfurt, Schleusenweg 2-16, 60528, Frankfurt am Main, Germany.

Superficial siderosis is a consequence of repetitive bleeding into the subarachnoid space, leading to toxic iron and hemosiderin deposits on the surface of the brain and spine. The clinical and radiological phenotypes of superficial siderosis are known to manifest over long time intervals. In contrast, this study defines the "acute superficial siderosis syndrome" and illustrates typical imaging and histopathological findings of this entity. Read More

Clin Neurol Neurosurg 2022 04 8;215:107188. Epub 2022 Mar 8.

Department of Neurosurgery, Stroke Center, Kokura Memorial Hospital, 3-2-1 Asano, Kokura kita-ku, Kitakyushu-city, Fukuoka 802-8555, Japan. Electronic address:

We report a case of a ruptured aneurysm of the posterior inferior cerebellar artery (PICA) communicating artery, which is an extremely rare condition, with only 10 other cases reported in the literature. We repaired the aneurysm by clipping combined with occipital artery-PICA (cortical segment) bypass. This surgical method reduces hemodynamic stress and may prevent recurrence or new occurrence of aneurysms in this region. Read More
