Introduction: 80–90% of insulinomas are smaller than 2 cm, equally located in the head, body and tail of pancreas. Computer tomography (CT) is 75%, magnetic resonance imaging (MRI) is 55–90%, endoscopic ultrasonography (EUS) is 85–95% and selective arterial calcium stimulation test (SACST) is 95–100% sensitive in the diagnosis of insulinomas. Here, we presented two cases of insulinoma which could not be located by conventional methods and evaluated with SAC...

Introduction: Insulinoma is a rare neuroendocrine tumor that is difficult to diagnose due to its obscure location. Conventional radiographic methods have low sensitivity and are inadequate to detect insulinoma. Selective arterial calcium stimulation test (SACST) is 95–100% sensitive in the diagnosis of insulinomas. Here, we presented two cases of insulinoma that could not be located by radiographic methods and evaluated them with SACST.Case 1: A 48-...
