Inflammatory myofibroblastic tumor of the pancreatic neck misdiagnosed as neuroendocrine tumor: A case report

Figure 1 Abdominal contrast-enhanced computed tomography. A: Axial non-contrast showed a low-density mass in the neck of the pancreas; B: Arterial phase indicated a distinct hypoattenuating mass; C and D: Venous phase revealed persistent hyperenhancement of the mass (magnetic resonance imaging is similar to computed tomography in enhancement mode and characteristics).
