Perflubron residua: 12 years following therapy.

Partial liquid ventilation therapy utilizing perfluorocarbons has been used for patients with severe respiratory distress. Perfluorocarbons such as perflubron have been demonstrated to clear from the lungs shortly after therapy. We present a 13-year-old boy with residual perflubron in his lungs, 12 years following therapy with perflubron. The imaging features are important to recognize as these patients return for additional care and imaging.
