Insulinomas are the most common islet cell tumor of the pancreas. They are usually small at clinical presentation and the diagnosis is mainly based on clinical and laboratory findings. Tumor localization may require several modalities, including ultrasonography, computed tomography (CT), magnetic resonance (MR) imaging, and angiography. We report a case of insulinoma at the cranial surface of the pancreas, which was not identified on axial but only on coronal MR imaging. The importance of coronal imaging in detecting such small pancreatic tumors is emphasized.
