Gastric involvement in autoimmune pancreatitis: MDCT and histopathologic features.

CONTEXT

Autoimmune pancreatitis is a relatively rare, yet well described cause of chronic pancreatitis. Extrapancreatic findings are now recognized as important manifestations of this entity and viewed as part of a larger disease process tentatively named "IgG4-associated sclerotic disease".

CASE REPORT

We herein report a case of autoimmune pancreatitis with histopathologically proven gastric involvement. We also describe and illustrate the multidetector-row computed tomography appearance of gastric involvement in IgG4-associated sclerotic disease.

CONCLUSION

Autoimmune pancreatitis is increasingly recognized as a multi-systemic disease whose early recognition dramatically affects patient management. Knowledge of the computed tomography appearance of gastric involvement in autoimmune pancreatitis can aid in diagnosis.
