Hypoechoic gallbladder polyps refer to polyps with strong echoes, which may be caused by cholesterol crystals or adenomas, etc. Polyps of 8mm are mostly benign and have a lower risk of gallbladder cancer. Gallbladder polyps refer to lesions protruding into the gallbladder cavity, which may be caused by neoplastic diseases such as adenomas and adenocarcinomas, or cholesterol polyps, inflammatory polyps, or adenomatous hyperplasia. Gallbladder polyps >10mm have a certain risk of malignancy and need to be distinguished from gallbladder cancer, while polyps of 8mm are more likely to be benign. Hypoechoic 8mm gallbladder polyps are usually caused by benign diseases, and can be reviewed by ultrasound regularly if there are no clinical symptoms. If the polyp is wide at the base, combined with stones or thickening of the gallbladder wall, or if the polyp is gradually increasing in size, it is necessary to pay attention to the presence of malignant lesions and perform cholecystectomy if necessary. Patients are advised to consult a specialist and follow the doctor’s instructions for further examination and treatment.
