Serum igG4 levels (checked after interpreting radiologist raised concern of igG4-related disease) = 1063 mg/dL (normal 8-140 mg/dL). Range of igG4 values in AIP = 1234 +/-13471.
What findings should make you think about autoimmue/igG4-related pancreatitis?
- diffuse pancreatic enlargement
- minimal peripancreatic inflammation/fluid
- concentric thickening and enhancement of the common bile duct, indicating autoimmune cholangitis
Timely diagnosis is of great benefit to patients, as they can usually be managed with steroids alone.
