Figure 14.

A 22-year-old woman with epithelial cyst arising from intrapancreatic accessory spleen. (A) Axial pancreatic phase CT image shows a 2.5 cm cystic lesion (arrow) with solid component (arrowhead) in the pancreatic tail. (B, C) MR images show that the signal intensity of the solid component (arrowhead) on T2-weighted image (B) and diffusion-weighted image (C) is closely similar to that of the spleen (open arrowhead) and different from that of the pancreatic tissue (open arrow). (D) Axial gadolinium-enhanced arterial phase MR image reveals zebra enhancement pattern of the solid component (arrowhead), like as spleen (open arrowhead). Note cystic portion (arrow) without enhancement.
