Gallbladder polyps: also known as gallbladder bulge-like lesions, is a term used in imaging of gallbladder disease, especially in diagnostic ultrasound findings. Ultrasound (most commonly known as B-mode ultrasound, or “B-ultrasound”), CT, and MRI are all indirect images of the organ. It is like the shadow of a person formed by the sun, male, female, old, young, it is not clear from the shadow alone, to a certain extent, you can see the height, fat, thin, etc.. Gallbladder polyp means that the lesion in the gallbladder is closely connected to the wall of the gallbladder, that is, it occurs in the wall of the gallbladder and does not move, or moves insignificantly, with the change of body position (in the case of gallbladder stones ultrasound image is strongly echogenic, posterior with acoustic shadow, which moves with the change of body position). From the clinical point of view, most of the gallbladder polyps are cholesterol polyps or “pseudo-polyps”, which means that they have the same composition as gallbladder stones and do not become cancerous, like limescale attached to the wall of the jug; the other type of “true polyps” is less common, i.e., lesions caused by hyperplasia of the gallbladder wall itself. The other type of “true polyp” is less common, which is the lesion caused by the hyperplasia of the gallbladder wall itself, and can become cancerous, rarely when it is less than 1 cm, but the cancer rate increases when it is larger than 1 cm. Ultrasound characteristics of cholesterol polyps: strong echogenicity, single or multiple, slow “growth”. True polyps: isoechoic or hypoechoic, solitary and fast growing. Of course, in order to make a clear diagnosis, we should also refer to other examinations and consider them together, so don’t be nervous when you encounter this situation, it is better to consult a specialist.
