Noninsulinoma pancreatogenous hypoglycemia syndrome in a Saudi male

Abstract

Nesidioblastosis is focal or diffuse islet hyperplasia leading to hyperinsulinism with subsequent hypoglycemia in the absence of insulinoma, usually described in neonates and infancy. We described the first adult case of nesidioblastosis in Saudi Arabia and the Gulf region. The diagnosis and treatment of the condition can be very difficult and challenging. Despite the fact that our patient responded initially to surgical treatment, his hypoglycemic symptoms occasionally recurred and needed adjunctive medical treatment. Although initially thought to affect only infants and children, cases of nesidioblastosis can affect adults and pose a diagnostic and therapeutic challenge to the clinicians.
