Conventional ultrasound | Fundamental powerDoppler sonography | Echo-enhancedsonography | |
Cystadenoma | • small cystic areas (often < 3 cm) | • no tumour vesselsdetectable | • highly vascularised tumour arteries along the fibrotic strands |
• spoke-like pattern of fibrotic strands with small calcifications | |||
• no dilated Wirsung's duct | |||
Cystadeno-carcinoma | • large cystic areas (often > 5 cm)• solid areas | • rarely tumour vesselswith chaotic pattern detectable | • poorly and chaotic vascularised solid areas |
• no dilated Wirsung's duct | |||
Pseudocyst | • often echo-free pattern | • rarely tumour vessels detectable in ”young cysts” | •”young cysts” (a few weeks of age) show often a highly vascular-ised wall |
• sharply delineated wall | |||
• features of acute and/or chronic pancreatitis | |||
• signs of bleeding and/or calcifica-tions• bowel infiltration is possible | •”old cysts” (a few months of age) show often a poorly vascularised wall |
