EFSUMB 2020 Proposal for a Contrast-Enhanced Ultrasound-Adapted Bosniak Cyst Categorization – Position Statement

Abstract

The well-established Bosniak renal cyst classification is based on contrast-enhanced computed tomography determining the malignant potential of cystic renal lesions. Ultrasound has not been incorporated into this pathway. However, the development of ultrasound contrast agents coupled with the superior resolution of ultrasound makes it possible to redefine the imaging of cystic renal lesions. In this position statement, an EFSUMB Expert Task Force reviews, analyzes, and describes the accumulated knowledge and limitations and presents the current position on the use of ultrasound contrast agents in the evaluation of cystic renal lesions.

Zusammenfassung

Die gut etablierte Bosniak-Klassifikation von Nierenzysten basiert auf der kontrastverstärkten Computertomografie, die das maligne Potenzial zystischer Nierenläsionen bestimmt. Die Sonografie wurde bei diesem Verfahren nicht berücksichtigt. Die Entwicklung von Ultraschallkontrastmitteln in Verbindung mit der überlegenen Auflösung im Ultraschall ermöglicht es jedoch, die Bildgebung zystischer Nierenläsionen neu zu definieren. In dieser Stellungnahme überprüft, analysiert und beschreibt eine Expertengruppe der EFSUMB das gesammelte Wissen und die Grenzen und präsentiert die aktuelle Position bezüglich des Einsatzes von Ultraschallkontrastmitteln bei der Bewertung zystischer Nierenläsionen.
