Abstract

Among various imaging studies used for localizing insulinoma, abdominal computed tomography (CT) is one of the most commonly used imaging tool for its non-invasiveness and high sensitivity of localizing insulinoma. However, if insulinoma is not localized by abdominal CT and still the patient is strongly suspicious for insulinoma clinically, other diagnostic tools for imaging including endoscopic ultrasound should be considered to detect insulinoma. We report a case of insulinoma diagnosed by contrast enhanced endoscopic ultrasound which was not detected by multiple phase contrast enhanced abdominal CT.
