Patient: Hello doctor, I had breast augmentation with autologous fat three years ago, and only the right side was done. Not long afterward, I found a hard lump in my right breast, which I have not cared about for three years because it is painless, and now I am ready to get married. During the premarital checkup, the doctor found the hard lump and suggested ultrasound. The ultrasound showed that the left breast glandular layer was 1.3CM thick, and the right breast glandular layer was 1.2CM thick, with patchy hypoechoic echoes and stripes of strong echoes, and several cystic areas in the right breast, the larger of which was located in the lower part of the inner nipple and 1.7*1.4CM, with clear borders, and a “nipple-like” bulge, 0.4*0.4CM in size. CDFI: no obvious blood flow signal was seen in and around the area. CDFI: there is no blood flow signal in or around it. There are no obvious enlarged lymph nodes in the axillae bilaterally. Can I have the necrotic fat mass surgically removed? What are the sequelae after removal? Is there any possibility of necrosis of the remaining fat? I am very worried and don’t know what to do, please ask my doctor for help. Patient: Because the hard lumps appeared shortly after my autologous fat breast augmentation back then, it was painless and I never cared about it. If I wasn’t getting ready to get married, I probably wouldn’t have taken it seriously. Now it’s scary after the ultrasound. When I consulted the doctor during the checkup, he said that the hard lumps might be produced by fat necrosis, and I am worried that if the hard lumps are removed, it will affect the remaining fat inside the breasts to continue to harden, is this possible, doctor? Dr. Wang Enli: Necrosis can occur after fat grafting, but it usually occurs within a short period of time after the surgery. Based on your ultrasound result, it looks more like intracapsular space-occupying lesion, if so, it is better to have a surgical biopsy. Patient: Is an intracapsular space-occupying lesion a cyst? Will there be any sequelae after surgical resection? Wang Enli: It is not a cyst so it is better to remove it. Patient: OK, thank you.
