Vascular pattern of solid pancreatic lesions (SPLs) has been investigated by different abdominal imaging modalities and by contrast-enhanced endoscopic ultrasonography (CE-EUS). Compared with surrounding pancreatic parenchyma three different patterns have been described: hypo-, iso-, and hypervascular. The majority of SPLs are hypovascular, and the diagnostic relevance of hypoenhanced pattern to predict pancreatic adenocarcinoma (PDAC) is well established. Differently, iso- and hypervascular pattern is not specific and can be expressed by several SPLs, with different clinical behavior and management. To date, poor is know about the role of EUS in differential diagnosis of non-hypovascular SPLs and features associated with malignancy.
