Differenzialdiagnose renaler Raumforderungen

ZusammenfassungDurch die Vielzahl von Ultraschalluntersuchungen sowie die moderne CT- und MRT-Diagnostik werden sehr häufig renale Raumforderungen zufällig in einem asymptomatischen Stadium entdeckt. Der Radiologe hat die Aufgabe, diese beim Erwachsenen weiter zu differenzieren und behandlungsbedürftige und maligne Raumforderungen zu erkennen. Die CT- und MRT-Bildgebung bieten hier die Möglichkeit, durch spezifische Zeichen der Tumoren eine weitere Charakterisierung vorzunehmen. Die wichtigsten renalen Raumforderungen werden aufgezeigt und typische bildmorphologische Kriterien erläutert.AbstractThrough the large numbers of ultrasound studies and computed tomography (CT) and magnetic resonance imaging (MRI) scans being done, many symptomless renal tumors are detected. The radiologist has a duty to differentiate renal lesions and diagnose malignant tumours in adults. Modern imaging modalities such as CT and MRI have the capability to further differentiate renal tumours by specific attributes. In this article, the most common renal tumours are presented, and typical findings are discussed.
