Lipomas can be accurately examined and diagnosed by ultrasound. Lipoma can be detected by color ultrasound in the clinic, which can see the echogenic adipose tissue structure, therefore, for the confirmation of the diagnosis of lipoma, ultrasound can locate and obtain the size and density of the patient’s lipoma, as well as the extent of the encroachment of the lipoma. For the lipoma detected, according to its size, the corresponding treatment is as follows: 1. If the lipoma is relatively small and has no obvious symptoms, it can be followed up regularly in the clinic, and regular ultrasound and physical examination can be done. 2. Larger lipomas can be treated by surgery, and after removing the lipoma, the incision can be re-incised and sutured, and cosmetic treatment can be adopted, such as liposuction to break up the fat particles of the lipoma after liposuction. 3. Lipoma can also be treated by cosmetic means, such as liposuction surgery, in which the fat particles of the lipoma are crushed and sucked out of the body.
