Near infrared light examination as part of the management of sporadic pancreatic head insulinoma: Case report

•77-Year-old female patient with the diagnosis of pancreatic head insulinoma.•We used near infrared light to detect synchronous pancreatic tumors.•Near infrared light was used to detect secondary lymph node, liver metastasis.•Was perform cephalic pancreatoduodenectomy.•Evolution was favorable. We report the case of a 77-year-old female patient with the diagnosis of pancreatic head insulinoma, in whom we used near infrared light (NIR) to detect synchronous pancreatic tumors and potential secondary lymph node or liver involvement. The patient presented with hypoglycemia manifesting by lipothymia. With the diagnosis of secretory neuroendocrine tumor (insulinoma) of the pancreatic head, cephalic pancreatoduodenectomy with the preservation of the pylorus was performed after NIR visualization of the pancreatic tumor mass. At 6, 12, 18 months postoperatively, the patient no longer had hypoglycemia and her general state was good. NIR with indocyanine green (ICG) evidences pancreatic neuroendocrine tumors, as well as possible synchronous tumors and secondary lymph node or liver involvement.
