Insulinome de haut grade découvert après 5 ans d’hypoglycémies graves

Functional endocrine tumors of the pancreas are rare. Among them insulinomas are the most common types. The majority of the patients with insulinoma are between 30 and 60 years of age and 59% of them are women. Most insulinomas are sporadic tumors while 10% of them develop in patients with multiple endocrine neoplasia (MEN). Diagnosis is based on clinical examination and laboratory tests. Preoperative imaging assessment (echo-endoscopy, CT, MRI) is essential for tumor localization in more than 80% of cases. Surgical excision is the treatment of choice. We here report the case of a 50-year old patient with high grade insulinoma developed on the anterior surface of the pancreas tail.
