Susceptibility weighted imaging at 1.5 Tesla magnetic resonance imaging in dogs: Comparison with T2*-weighted gradient echo sequence and its clinical indications.

Vet Radiol Ultrasound 2020 Sep 14;61(5):566-576. Epub 2020 Jul 14.

Willows Referral Centre, Solihull, UK.

Susceptibility weighted imaging (SWI) is a high resolution, fully velocity-compensated, three-dimensional gradient echo (GE) MRI technique. In humans, SWI has been reported to be more sensitive than T2*-weighted GE sequences in the identification of both intracranial hemorrhage and intra-vascular deoxyhemoglobin. However, published clinical studies comparing SWI to T2*-weighted GE sequences in dogs are currently lacking. Read More

Traumatic microbleeds suggest vascular injury and predict disability in traumatic brain injury.

Brain 2019 11;142(11):3550-3564

Center for Neuroscience and Regenerative Medicine, Bethesda, Maryland, USA.

Traumatic microbleeds are small foci of hypointensity seen on T2*-weighted MRI in patients following head trauma that have previously been considered a marker of axonal injury. The linear appearance and location of some traumatic microbleeds suggests a vascular origin. The aims of this study were to: (i) identify and characterize traumatic microbleeds in patients with acute traumatic brain injury; (ii) determine whether appearance of traumatic microbleeds predict clinical outcome; and (iii) describe the pathology underlying traumatic microbleeds in an index patient.

Pseudohypoxic Brain Swelling: Report of 2 Cases and Introduction of the Lentiform Rim Sign as Potential MRI Marker.

World Neurosurg 2020 Jan 10;133:221-226. Epub 2019 Oct 10.

Department of Radiology and Interventional Neuroradiology, Isfahan University of Medical Sciences, Isfahan, Iran.

Background: A rare but important complication related to otherwise uneventful brain and spine surgery is becoming more recognized and more frequently reported in the medical literature. This has been variably labeled as pseudohypoxic brain swelling or postoperative hypotension-associated venous congestion. This poorly understood condition occurs in the setting of surgical intervention and is thought to be related to cerebrospinal fluid leak or evacuation, decreased intracranial pressure, and subsequent development of deep venous congestion affecting the basal ganglia, thalami, and cerebellum.

[A Case of Meningitis Caused by Globicatella sanguinis in a Patient with a Lumbo-peritoneal Shunt].

Mikrobiyol Bul 2019 Jul;53(3):343-347

Sivas Cumhuriyet University Faculty of Medicine, Department of Neurosurgery, Sivas, Turkey.

Globicatella sanguinis is catalase-negative, alpha-hemolytic, nonmotile, facultative anaerobic grampositive cocci, identified as a new species in 1992. Since the colony morphology in blood agar and microscopic appearance resembles streptococci, it is thought that some of the isolates previously identified in the Streptococcus viridans group were G.sanguinis species.

Postobliteration Arteriovenous Malformation Mimicking Malignant Change 30 Years After X-Knife Treatment-Case Report and Review of Literature.

World Neurosurg 2019 Aug 10;128:169-173. Epub 2019 May 10.

Division of Neurosurgery, Department of Surgery, Chimei Medical Center, Tainan, Taiwan; Department of Biotechnology, Southern Taiwan University of Science and Technology, Tainan, Taiwan. Electronic address:

Background: Arteriovenous malformations (AVMs) are potentially dangerous vascular anomalies of the brain that can cause seizures or intracranial hemorrhage in patients if left untreated. Because full excision of these lesions is not always possible in deep or eloquent areas of the brain, radiosurgical advances have gone a long way in the control and treatment of AVMs. Postradiosurgery AVMs are followed closely via outpatient clinics with serial imaging every few months to assess AVM obliteration.

MR Imaging for Assessing Injury Severity and Prognosis in Acute Traumatic Spinal Cord Injury.

Radiol Clin North Am 2019 Mar 17;57(2):319-339. Epub 2018 Nov 17.

Department of Neurological Surgery, University of California, San Francisco, 505 Parnassus Avenue, Room M779, San Francisco, CA 94143, USA; Brain and Spinal Injury Center, Zuckerberg San Francisco General Hospital, 1001 Potrero Avenue, San Francisco, CA 94110, USA.

T2-weighted (T2W) imaging is the most important sequence for detection of acute traumatic spinal cord pathology in clinical practice. Intramedullary hemorrhage on T2W imaging is associated with some component of irreversible injury and arguably the most robust MR imaging predictor of injury severity. The MR imaging appearance of the injured spinal cord in the early stages of injury is highly dynamic, and the time delay from injury to imaging must be considered in image interpretation. Read More
