Pancreatic tail bulge may be caused by inflammation, pancreatic cysts, pancreatic duct blockage, malignant lesions and other reasons. 1. Inflammation: when suffering from pancreatitis, repeated stimulation of inflammation can lead to localized edema, congestion and other abnormalities of the pancreas, which can be manifested in the tail of the pancreas, causing the symptom of pancreatic tail bulge. 2. Pancreatic cysts: due to the invasion of tumor cells on the pancreatic parenchyma and organs, the volume of the tail of the pancreas can be significantly increased, manifested as symptoms of pancreatic tail bulging. 3. Pancreatic duct blockage: bacterial infection, stones and other reasons can cause pancreatic duct blockage, resulting in obstruction of pancreatic juice discharge, which can cause localized enlargement of the pancreas, thus manifesting as bulging of the tail of the pancreas. 4. Pancreatic tail occupying malignant lesions: mainly pancreatic cancer and pancreatic endocrine tumors, which can lead to pancreatic tail bulging. If you have pancreatic tail bulge, you need to go to the regular hospital in time for relevant examination, after clarifying the specific cause, and then follow the doctor’s instructions to treat it actively.
