Introduction: A 56-year-old woman was submitted to caudal pancreatectomy for an insulin-secreting adenoma suspected by MRI and fast test positivity at 38th hour. Intraoperative US excluded other pancreatic lesions but tissue analysis described a 8mm neuroendocrine well-differentiated tumor and the surrounding pancreatic tissue exhibited characteristics of nesidioblastosis. Five months after surgery, she still reported episodes of hypoglycemia requiring diazoxide therapy and she was admitted to our department.
