Pancreatic<unk>  has a variable appearance on USG. The appearance relative to normal pancreatic tissue may be hypoechoic, isoechoic or hyperechoic. In majority of the cases, an ill defined hypoechoic mass is seen infiltrating into a bright pancreatic parenchyma.  Pancreatic and biliary duct dilatation is seen in case of carcinoma of the head of pancreas (Double duct sign). The disadvantage of a transabdominal USG is its inability to clearly demarcate lymphadenopathy, tumor margins and the relation of the tumor to vessels around the pancreas. Endoscopic Ultrasound (EUS) has a high efficacy in the detection of tumors smaller than 2 cm, for local T and N staging, and prediction of vascular invasion. It has a higher resolution than transabdominal ultrasound, due to the small distance between the endoscope and pancreas through the wall of the duodenum. EUS plays an important role in the preoperative staging of pancreatic<unk>  particularly in cases where CT evaluation suggests equivocal findings. Moreover, EUS-guided fine needle aspiration biopsy (FNA) is the best modality for obtaining a tissue diagnosis.
