Cyst Aspiration

During a cyst aspiration, a needle is placed in the lump in the breast, usually using ultrasound guidance. Fluid is then drained with anticipation that a lump (detected by an X-ray mammogram) will disappear. A post-aspiration mammogram may be recommended or air may be injected back into the cyst cavity to more clearly visualize the cyst wall. Sometimes this procedure, which is also called a pneumocystogram, is performed to inhibit cysts from recurring.
