Figure 1: Imaging changes before and after steroid therapy in patient No. 6. Pretreatment: the arterial phase (a) and venous phase (b) of contrast-enhanced computed tomography both revealed a diffusely swollen pancreas with a “capsule-like rim” and “sausage-like” appearance. After internal drainage and a 3-month steroid therapy, the arterial phase (c) and venous phase (d) of contrast-enhanced showed that the swollen status of pancreas had been obviously reduced.
