Hypertensive Crisis in a Young Man During Micturition: Contrast-Enhanced Ultrasound for Diagnosis of Paravesical Paraganglioma

G. Meyer

Paragangliomas are rare extraadrenal neoplasms of the sympathetic nervous system, which seldom may arise in the sympathetic plexus of the urinary bladder wall. Some of these tumors are producing catecholamines. To avoid serious complications including hypertensive crisis during operation, it is important to consider these tumors in the differential diagnosis of paravesical tumors. Here, G. Meyer presents the ultrasound and contrast-enhanced ultrasound findings of a paravesical paraganglioma.

Special Echocardiographic Diagnosis and Specific Problem Constellations in Patients with Degenerative Stenosis of the Aortic Valve

A. Hagendorff, S. Stöbe, A. Tarr, D. Pfeiffer

Study goals
Even when a thorough transthoracic echocardiographic examination is performed, it is often still difficult to assess the severity of the defect and to make subsequent therapeutic decisions based on the findings. The goal of this publication is to present the reader with options in addition to conventional echocardiography for the echocardiographic diagnosis of patients with degenerative stenosis of the aortic valve. These methods include not only transesophageal echocardiography and stress echocardiography, but also modern applications of deformation imaging. Furthermore, problem constellations and possible errors in the echocardiographic diagnosis of aortic valve stenosis will be outlined.

EFSUMB Guidelines and Recommendations on the Clinical Use of Ultrasound Elastography.Part 2: Clinical Applications

D. Cosgrove, F. Piscaglia, J. Bamber, J. Bojunga, J.-M. Correas, O. H. Gilja, A. S. Klauser, I. Sporea, F. Calliada , V. Cantisani , M. D'Onofrio, E. E. Drakonaki, M. Fink , M. Friedrich-Rust , J. Fromageau, R. F. Havre , C. Jenssen, R. Ohlinger , A. Săftoiu, F. Schaefer , C. F. Dietrich

The clinical part of these Guidelines and Recommendations produced under the auspices of the European Federation of Societies for Ultrasound in Medicine and Biology assesses the clinically used applications of all forms of elastography, stressing the evidence from meta-analyses and giving practical advice for their uses and interpretation. Diffuse liver disease forms the largest section, reflecting the wide experience with transient and shear wave elastography . Then follow the breast, thyroid, gastro-intestinal tract, endoscopic elastography, the prostate and the musculo-skeletal system using strain and shear wave elastography as appropriate. The document is intended to form a reference and to guide clinical users in a practical way.

Discordant Elastography Images of Breast Lesions: How Various Factors Lead to Discordant Findings

J. H. Yoon, M. J. Kim, E.-K. Kim, H. J. Moon, J. S. Choi

Yoon et al wanted to evaluate the rate of the elastography-pathology discordance, and evaluate which various factors have an effect on discordant elastography images (DEI) of breast lesions.

Quantitative Assessment of Bone Microvascularization After Osteocutaneous Flap Transplantation Using Contrast-Enhanced Ultrasound (CEUS)

S. Geis, L. Prantl, S. Mueller, M. Gosau, P. Lamby, E. M. Jung

Extensive wound defects frequently have to be covered by free flap transplantation. A monitoring device for measuring capillary level perfusion of bone is currently not available. The aim of the study was to detect complications after osteocutaneous flap transplantation using contrast-enhanced ultrasound (CEUS). Additionally quantitative analysis was performed by special perfusion software (QONTRAST®; Bracco, Italy).

Characterization of Primary and Recurrent Nodules in Liver Cirrhosis Using Contrast-Enhanced Ultrasound: Which Vascular Criteria Should Be Adopted?

S. Leoni, F. Piscaglia, A. Granito, A. Borghi, M. Galassi, S. Marinelli, E. Terzi, L. Bolondi

The aim of Leoni et al was to assess the impact of different vascular patterns at contrast-enhanced ultrasound (CEUS) on the characterization of small liver nodules (10– 30 mm) in cirrhosis and to determine whether primary nodules and recurrent nodules (after a previously treated hepatocellular carcinoma) display variations in enhancement pattern.
