The echoes of ectopic pancreas under color ultrasound are uniform isoechoic or hyperechoic nodules in the gastrointestinal wall, which are round or flat, small in size, with clear borders, and the tubular structure of fibers can be seen inside them, and blood flow signals can be detected. Ectopic pancreas is a congenital developmental abnormality, which refers to the independent pancreatic tissue located outside the normal pancreatic anatomical position. Its clinical symptoms often lack specificity and are easily confused with gastrointestinal tumors. It can be differentiated from gastrointestinal mesenchymal tumors in that although both are blood-rich masses, mesenchymal tumors are large in size, irregular in shape, often hypoechoic, and most of them are ectopic or mixed in growth. When ectopic pancreas is suspected, it is necessary to consult a doctor in time and improve relevant examinations for identification and active treatment.
