title: Breast cyst recurrence after postaspiration injection of air.
abstract: Breast cysts are a common cause of breast pain, lumps, and patient anxiety. Older studies incidentally reported a decrease in cyst recurrence when air was injected for diagnostic purposes after aspiration. The purpose of this study was to determine the incidence of cyst recurrence after ultrasound-guided aspiration and injection of air for therapeutic purposes. In this study, we retrospectively reviewed 113 cysts aspirated in 90 women; 88 had air injected for therapeutic purposes after aspiration, and 25 did not. Subsequent mammograms and sonograms were reviewed (mean follow-up 21 months, range of 8-36 months) to assess for recurrence. Demographic and imaging features were not different between the two study groups. Of the 88 cysts that had air injected after aspiration, 14 recurred (16%) compared with 20 of 25 cysts (80%) that did not have air injected following aspiration. Cyst recurrence correlated with air injection, but did not correlate with cyst size, menopausal status, or use of hormone replacement therapy. Only one patient complained of pain, and no complications occurred. The injection of air into cysts following aspiration may be useful for therapeutic purposes.
