Pancreatic volume change using three dimensional-computed tomography volumetry and its relationships with diabetes on long-term follow-up in autoimmune pancreatitis

Figure 3 Portal venous contrast-enhanced computed tomography images of 59-year-old man with diffuse-type autoimmune pancreatitis. A: Initial computed tomography showing diffuse enlargement of the pancreas with capsule-like rim (arrowheads); B: One month later, pancreatic volume had decreased (relative volume change 683%) and capsule-like rim was observed; C: Six months later, pancreatic volume had decreased further (relative volume change 207%) and no capsule-like rim was observed; D-F: Relative volume changes after 12, 54 and 86 months were 224%, 21.5% and 20.6%, respectively.
