Radiation recall pneumonitis

Radiopaedia • CC-by-nc-sa 3.0 • de

Radiation recall pneumonitis (RRP) is a rare reaction occurring in previously irradiated areas of pulmonary tissue after the application of triggering agents (e.g. chemotherapeutic agents or immunomodulators etc). It is not thought to be due to the direct effect of radiation. Classically this has been described with taxanes, anthracyclines, gemcitabine, erlotinib and nivolumab .
