Imaging of gastroenteropancreatic neuroendocrine tumors

Figure 1 Axial contrast enhanced computed tomography image. A: The primary lesion arising from a loop of the ileum, with extension along the mesenteric border. Typical central stipple calcification is evident; B: In the arterial phase showing multiple hypoenhancing bilobar lesions in a non-cirrhotic liver consistent with neuroendocrine tumor metastases; C: In the equilibrium phase showing the typical washout pattern of the lesions corresponding to that in (B).
