Figure 1: Linear EUS showing an inhomogeneous hypoechoic mass with irregular borders in the head of the pancreas. The echotexture of the pancreatic parenchyma appears heterogeneous with a coarse reticular pattern. A single pancreatic duct (PD) with a maximal diameter of 4 mm could be delineated in the head of the pancreas, appearing uniform with anechoic margins. A patent portal vein (PV) was also depicted bellow the PD with no evidence of tumor invasion.
