Type III gastric carcinoid in a 39-year-old man with carcinoid syndrome. (a) Axial contrast-enhanced CT shows a solitary homogeneous exogastric mass (arrow) arising from the lesser curvature with multiple calcific foci within it (arrowhead). (b) Axial T1-weighted and (c) T2-weighted MRI shows the mass (arrow) to be hypointense on the T1-weighted image and mildly hyperintense on the T2-weighted image. (d) Contrast-enhanced arterial phase MRI reveals the mass (arrow) is intensely hypervascular.
