Das Kontrastverhalten des Leberangiomyolipoms in der echosignalverstärkten Power-Dopplersonographie

Abstract

Angiomyolipomas of the liver are rare tumours. Differentiation from other liver lesions using imaging techniques is difficult. This is the first report describing the contrast behaviour of an angiomyolipoma of the liver with echo-enhanced power-Doppler sonography. A rapid signal enhancement of the arteries within the tumour and an immediate drainage of the blood into the liver veins was demonstrated. Furthermore, spectrums similar to av-fistulas could be detected. Portal venous blood flow, irregular calibre of the vessels or chaotic vascular patterns could not be found.
