Ultrasound diagnosis of pancreatic tumors: pancreatic retroperitoneal across in front of the first lumbar 1_2. Pancreas separately, neck, body and tail of four parts, pancreas shape varies, the variation can be divided into four types: the clam bucket type, sausage type, dumbbell-shaped type and propeller.
Deep parts of the pancreas, gastrointestinal tract and easy gas and food by the interference of the ultrasonic set of check. Therefore, fasting before the test should be to minimize the interference of the stomach of food and gas, such as the gas too much water can be an empty stomach drink 500_800ml make the stomach full of liquid through the acoustic window as the pancreas to display clearly.
1. Pancreatic cyst
Pancreatic cysts can be divided into true cysts and pseudocysts. True cysts are the following: congenital polycystic disease, who was part of, often associated with liver, kidney, spleen and the performance of multiple organ cysts; obstructive cyst membrane, in the tracing process can change the situation with the obstruction change; pancreatic secretion of certain tumor itself or blocking membrane, and central necrosis can be formed when the cyst.
Most pseudocyst complications of acute pancreatitis, inflammatory exudates or tissue necrosis was caused. Sonographic characteristics of its membrane gland volume increased or normal, the pancreas can be seen a single or a few dollars echo area, outline clear, posterior echo enhancement, if it is inflammatory exudate, necrosis caused by the pseudocyst, the general number days or a few months will go away.
Ultrasound diagnosis of pancreatic cancer 2. Pancreatic Cancer
Is a relatively common malignancy, occur in the film head, but the film body, the membrane tail may also occur. The ultrasonographic appearance of focal prostate volume for the film increases, the film is not the whole gland shape or contour is unclear, the tissue around the cancer was Crab-like invasion.
Tumor site can be out processes, the lesion was hypoechoic mass can be, strong or weak echo mass uneven and irregular, can be lobulated, perimeter unclear; if the tumor is located in the common bile duct by the first film pressure caused by bile duct dilatation, cholestatic, membrane expansion phenomenon. Adenocarcinoma of the film is often transferred, should be carefully observed adjacent organs and the surrounding lymph nodes, when found to have metastases, the film is more reliable diagnosis of adenocarcinoma.
