摘　　要：Although insulinomas are rare, they are the most com-mon pancreatic neuroendocrine tumor, with an inci-dence of four cases per million population. Insulinomas are generally benign indolent intrapancreatic tumors. Surgical resection remains the main option for treat-ment. However, up to 67% of a pancreatic head insu-linomas are nonpalpable, thus surgical resection of the nonplapable insulinoma in this area could become prob-lematic resulting in prolonged surgical time, increased risk of pancreatic duct injury and need for pancreati-coduodenectomy. Endoscopic ultrasound-guided fine- needle tattooing(EUS-FNT), has been shown to have a crucial role for localization of pancreatic body and tail lesions, facilitating laparoscopic distal pancreatectomyand helping surgeons identify the location of the tumor. EUS-FNT might have a role for preoperative localiza-tion of pancreatic head insulinomas which are likely to be nonpalpable. We report a case of preoperative EUS-FNT for localization of a nonplapable pancreatic head insulinoma. This report demonstrates that EUS-FNT of pancreatic head insulinomas may facilitate surgical resection, reduce operative time and decrease surgical complications.Although insulinomas are rare, they are the most com-mon pancreatic neuroendocrine tumor, with an inci-dence of four cases per million population.
