We report our recent experience of successful ultrasonography-guided catheter drainage of a huge retro-mammaryabscess in a 27-year-old female patient with pulmonary tuberculosis. For breast abscesses, the pro-cedure can beused instead of surgery. Its merits are that it is easy and cost-effective, there is less scar forma-tion,outpatient management may be possible, and in reported cases there has been no recurrence.
