Application of Contrast-Enhanced Ultrasound in Cystic Pancreatic Lesions Using a Simplified Classification Diagnostic Criterion

Figure 4

Pancreatic lesion was detected by physical examination. (a) US indicated a hyperechoic lesion in the pancreatic neck (M: mass; P: pancreas). The multiple microcysts were observed (arrows). The case was diagnosed as type IV by US. (b) The lesions showed heterogeneously enhancement in CEUS (the right picture). There were small cystic nonenhancement areas in the lesion (arrow). The case was diagnosed as type IV by CEUS. (c) Enhanced CT indicated no enhancement in the majority of the lesion. The fine septa enhancement could be seen (arrow) and type II was suspected by CT. (d) The surgical specimen was observed with a honeycomb shape with multiple compartments in the lesions. The case was pathologically diagnosed as microcystic SCNs.
