Calcification density of 2.1cmX2.3cm in the head of the pancreas indicates that calcification in the head of the pancreas may be caused by a variety of diseases such as chronic pancreatitis or pancreatic tumors. 1. Chronic pancreatitis: It is a chronic inflammatory disease caused by various reasons, resulting in changes in the function of pancreatic tissues, which may lead to calcification in the head of the pancreas, and may be accompanied by nausea, vomiting, abdominal distension and other symptoms. 2. Pancreatic tumors: benign and malignant tumors, such as pancreatic ductal adenocarcinoma, are common tumors in the digestive tract, which may cause calcification in the head of the pancreas, and may be accompanied by abdominal pain, decreased appetite, epigastric discomfort and other symptoms. According to the clinical symptoms of the patients, we need to improve the relevant examination under the guidance of doctors, and then carry out standardized treatment to avoid the condition from becoming more serious.
