Figure 2. Magnetic resonance imaging (MRI) results show that the morphology of the pancreas is normal. However, the tail of the pancreas shows irregular long T1 and long T2 signals with a maximum diameter of 1.4 cm, well-defined boundaries, and a continuous enhancement of the arterial phase. Positron emission tomography-computed tomography is recommended because MRI cannot identify the nature of the lesion. The suspicious lesion is indicated by the arrow. (A) T2; (B) T1 early arterial phase; (C) T1 extended phase; (D) T2 fat suppression phase; and (E) T1 late arterial phase.
