Air in the Breast: A Rare Cause of Iatrogenic Pneumomastia

Air in the breast tissue (pneumomastia) is a rare finding, more so without any history of procedures on the breast. We report the case of an 80-year-old lady who was found to have foci of gas in her right breast on a CT scan. On exclusion of other possible causes for the same, it was concluded that the air in the breast tissue was secondary to a peripheral intravenous line placement. To our knowledge, this is the first reported case of pneumomastia as a complication of peripheral intravenous line placement.
