Aortic dissection albeit negative d-dimers and zero clinical probability - Another facet of medicine's deadly chameleon.

J Cardiol Cases 2017 Feb 16;15(2):53-55. Epub 2016 Nov 16.

Technische Universität Dresden, Heart Center Dresden, University Hospital, Dresden, Germany.

Aortic dissection, the rupture of the aorta's intimal and medial layers, leading to the formation of a false lumen, is a relatively common disease with high mortality. So far, while not addressing penetrating aortic ulcer or intramural hematoma, current guidelines take a negative value for d-dimers for a sufficient method to rule out aortic dissection in patients with a low clinical probability, as calculated by the ADD risk score. We present two cases of patients with acute aortic dissection, albeit presenting with a low clinical probability for acute aortic dissection and negative values for d-dimers. Read More

The spectrum of cloacal malformations: how to differentiate each entity prenatally with fetal MRI.

Pediatr Radiol 2018 Dec 13. Epub 2018 Dec 13.

Department of Diagnostic Radiology, Division of Pediatric Radiology,, Children's Hospital Colorado,, 13123 East 16th Ave., Mailbox B-463,, Aurora, CO, 80045, USA.

The term cloacal malformation is commonly used to describe the classic cloacal malformation where there is a single common urogenital and intestinal channel located at the expected site of the urethra. There is, however, a spectrum of cloacal abnormalities that differ from this classic type and are less well discussed in the radiologic and surgical literature. The aim of this pictorial essay is to familiarize radiologists with the anatomy, appropriate terminology and key prenatal imaging findings that differentiate the six entities that constitute the spectrum of cloacal abnormalities.

Gadolinium-enhanced imaging of pediatric thoracic lymphoma: is intravenous contrast really necessary?

Eur Radiol 2018 Dec 13. Epub 2018 Dec 13.

Department of Diagnostic and Interventional Radiology, University Hospital Frankfurt, Theodor-Stern-Kai 7, 60590, Frankfurt/Main, Germany.

Objectives: Increasing awareness of potential side effects from gadolinium-based contrast agents has underlined the need for contrast-free magnetic resonance imaging (MRI). Numerous recent articles evaluated the risk of potential brain deposits, with the result that research is putting the focus more on alternative unenhanced imaging techniques. The aim of this study was to determine the need for contrast media for chest MRI in primary staging and follow-up care of lymphoma. Read More

Clinical Application of Diagnostic Imaging of Chiari-Like Malformation and Syringomyelia.

Front Vet Sci 2018 28;5:280. Epub 2018 Nov 28.

School of Veterinary Medicine, Faculty of Health & Medical Sciences, University of Surrey, Guildford, United Kingdom.

Chiari-like malformation (CM) and syringomyelia (SM) is a frequent diagnosis in predisposed brachycephalic toy breeds since increased availability of MRI. However, the relevance of that MRI diagnosis has been questioned as CM, defined as identification of a cerebellar herniation, is ubiquitous in some breeds and SM can be asymptomatic. This article reviews the current knowledge of neuroanatomical changes in symptomatic CM and SM and diagnostic imaging modalities used for the clinical diagnosis of CM-pain or myelopathy related to SM.
