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

Figure 4 Portal venous contrast enhanced-computed tomography images of a 60-year-old man with diffuse-type autoimmune pancreatitis and re-enlargement during follow-up. A: Initial computed tomography showing diffuse enlargement of the pancreas with capsule-like rim (arrowheads); B: Three years later, pancreatic volume had markedly decreased (relative volume change 414%); C: Seven years later, re-enlargement (diffuse type) of the pancreas with capsule-like rim (arrowheads) was observed (relative volume change 575%); D: One year after re-enlargement, pancreatic volume had decreased again (relative volume change 241%; arrows).
