A 67-year-old man with type 2 diabetes, unintentional weight loss, and increasing fasting blood glucose levels showed diffuse enlargement of the pancreas with peripheral hypoenhancement but no discrete mass on CT scan and soft tissue surrounding the abdominal arteries and left ureter causing hydronephrosis. Testing showed no pancreatic malignancy, no abnormal findings on colonoscopy, and lab results showed elevated IgG4. How would you interpret the test results?
