Gallbladder adenomyosis 14mm*9 refers to the size of the extent of gallbladder glandular as well as muscular layer hyperplasia on imaging, and 14mm*9 indicates that the size of the lesion is 14mm x 9mm. Adenomyosis is a benign, proliferative gallbladder disease of unknown origin, mainly characterized by hyperplasia of the gallbladder glands and the muscularis propria, with the gallbladder glands penetrating deep into the muscularis propria, causing ultrasound or other imaging manifestations. If adenomyosis of the gallbladder is detected, cholecystectomy is recommended for a limited period of time because of the possibility of malignancy. If there are symptoms of cholecystitis, including abdominal pain, nausea, vomiting, or rapid growth of gallbladder stones, timely surgical treatment may be considered, and laparoscopic cholecystectomy is usually recommended. If adenomyosis of the gallbladder is detected, it is recommended to actively consult the doctor and follow the doctor’s instructions for treatment.
