Breast pseudoaneurysm is a very rare complication. In this study, we report a patient with huge breast pseudoaneurysm after ultrasound-guided vacuum-assisted biopsy (UGVAB) of breast nodules. In treatment, we used microwave ablation to treat the pseudoaneurysm, and then used UGVAB again to eliminate the complicated hematoma. The patients obtained good therapeutic effect. From this case, we experience that, before the interventional operations for breast nodules, the systematic ultrasound examination should be performed. In the needle entering channel, the obvious blood vessels should be avoided to reduce the unnecessary vascular injury. When the pseudoaneurysm occurs, the patient's condition, pseudoaneurysm situation and hematoma size should be comprehensively considered, combined with the multidisciplinary consultation, for selecting the best treatment strategy.
