Symptoms: sudden onset of severe, steady abdominal pain, nausea and vomiting, jaundice may develop if inflammation cause blockage in the common bile duct. Us and ct most precisely define the degree of pancreatic inflammation. Both size and parenchyma echogenicity of the gland changed. Chronic pancreatitis: frequent intermittent injury to the pancreas causing increasing damage that produces scar tissue.
