We performed contrast‐enhanced color Doppler endoscopic ultrasonography in a 78‐year‐old patient with pancreatic cancer. Extracorporeal ultrasound demonstrated dilatation of both the intra‐ and extrahepatic bile ducts; however, the cause of obstructive bile‐duct change was not clarified. Endoscopic ultrasonography was performed in the routine manner and demonstrated a small tumor in the head of the pancreas. Before Levovist administration, there were no color signals detected in either the tumor or the pancreatic parenchyma. After administration of the agent, color signals began to emerge only in the pancreatic parenchyma surrounding the cancer tumor. There was still a lack of color signals inside the tumor. It is suggested that detailed hemodynamic changes that were not apparent by the conventional method could be identified by the contrast method under endoscopic ultrasonography.
