摘要
Abstract
Chronic mass-forming pancreatitis usually included two pathological types: Ordinary chronic mass-forming pancreatitis, characterized by granulation tissue with fibrosis and mass-forming autoimmune pancreatitis, characterized by a dense lymphoplasmacytic infiltration with extensive fibrosis and proliferation. Sometimes it was very difficult to identify pancreatic cancer from chronic mass-forming pancreatitis in the clinical practice. Accurate preoperative diagnosis and differentiation were extremely important for their treatment and prognosis. Chronic mass-forming pancreatitis and pancreatic cancer had their own characteristic imaging findings in CT and MRI respectively, especially in the dynamic contrast-enhanced MRI and DWI. A signal intensity-time (Sl-T) curve with a slow rise followed by a slow decline usually indicated chronic mass-forming pancreatitis, while a SI-T curve with a gradual rise indicated pancreatic cancer. ADC values in chronic mass-forming pancreatitis usually was lower than that in pancreatic cancer.关键词
