Solid occupations of the head of the pancreas are classified into two main possibilities as a benign mass or a malignant tumor of the head of the pancreas, rather than being differentiated by grading. Solid occupancy of the head of the pancreas refers to the growth of a mass in the area of the head of the pancreas, while solid occupancy has the possibility of a benign mass or a malignant tumor. Benign masses mainly refer to pancreatic adenoma, pancreatic lipoma, pancreatic cystadenoma, and mucinous cystadenoma. While pancreatic cancer accounts for a higher percentage of malignant tumors. When occupying lesions are found in the head of the pancreas in clinical practice, it is necessary to carry out enhanced CT examination, according to the patient’s clinical symptoms whether there is jaundice, ca199 and other tumor indexes, and if necessary, carry out pathological testing to exclude the existence of pancreatic malignant tumors. When occupying lesions are found in the pancreas, it is recommended to consult the Hepatobiliary Surgery Department of regular hospitals.
