[Differential diagnosis of frequent pancreatic tumours with echo-enhanced power-Doppler sonography - presentation of case reports].
The echo-enhanced Power-Doppler sonography is useful for the differential diagnosis of pancreatic tumours. Tumour criteria for the differentiation of pancreatic tumours with this procedure are explained using selected cases in the present publication. Ductal carcinomas are often hypovascularised compared with the surrounding tissue. On the other hand, neuroendocrine tumours are hypervascularised lesions. Tumours associated with pancreatitis have a different vascularisation pattern depending on inflammation and necrosis. Cystadenomas frequently show many vessels along the fibrotic strands.


CONCLUSIONS
Pancreatic tumours have different vascularisation patterns in the echo-enhanced Power-Doppler sonography. These characteristics can be used for the differential diagnosis.
