ABSTRACT

Insulinomas are islet cell tumors of the pancreas that produce hypoglycemic symptoms due to inappropriate insulin secretion. They appear generally as solitary adenomas, and less commonly as multifocal microadenomas or malignant insulinomas. Their incidence is approximately one case per one million population per year, and they appear mostly in patients over thirty years old. They are mainly situated in the tail or body of the pancreas. The diagnosis is based on the symptoms related to hypoglycemia, a blood glucose level under 50 mg/dL and high levels of fast insulin and C-peptide. Selective angiography is the best preoperative procedure to localize the tumor. Occult adenomas, which cannot be represented by preoperative imaging diagnosis, are detectable through intraoperative methods. Primary treatment of insulinoma is surgical resection of the tumor. When it fails or is contraindicated, medical treatment should be considered. We present acase of a patient with an insulinoma detected by an endoscopic ultrasound and a brief discussion of this disease.
