Case in brief

A 68-year-old woman with a 10-year history of recurrent hypoglycemic syncope had confirmed endogenous hyperinsulinemia. Conventional imaging and laparoscopic exploration of the pancreas did not identify a lesion. 18 F-NOTA-exendin-4 PET/CT showed an intense solitary focus in the para-aortic abdominal region. Surgical resection confirmed an ectopic insulinoma, and the hypoglycemia resolved postoperatively.

What made this case unusual

The insulinoma was solitary and ectopic, with no concurrent pancreatic or gastrointestinal lesion, and remained occult on conventional imaging and pancreatic exploration.

Diagnostic / clinical pearl

In this case, 18 F-NOTA-exendin-4 PET/CT localized an ectopic insulinoma after conventional imaging and pancreatic exploration were unrevealing.
