              | Malignant neuroendocrine tumor | Feb 23, 2009 |  |  
        | A 61-years-old man with a hypoechoic, inhomogeneous mass of the pancreatic body, with rich pulsatile vascularization, especially visualized after contrast-enhanced EUS (Sonovue). The tumor invaded the celiac trunck, splenic artery and splenic vein (T4). Multiple peripancreatic lymph nodes were also visualized. EUS-guided FNA was performed and the cytological exam revealed small round cells with severe nuclear atypia. |  |  |

              | Malignant neuroendocrine tumor | Feb 23, 2009 |  |  
        | Large tumor mass of the pancreatic tail discovered in a 55-years-old woman, visualized by EUS as a hypervascular mass in color Doppler or power Doppler mode. EUS-guided FNA established the diagnosis of neuroendocrine tumor, while immunohistochemistry of the cell-blocks was also positive. |  |  |
