Several studies have reported the findings of FDG-PET in benign lung disease with diffusepulmonary injury, but the characteristics and effectiveness of FDG-PET imaging for interstitialpneumonitis have not been substantiated. We report two cases of drug-induced pneumonitis in twopatients treated for breast cancer who were diagnosed by FDG-PET examination.Both of these cases showed diffuse interstitial infiltration in the bilateral lungs on CT, but thedegree of FDG accumulation was different. It is probable that the degree of FDG accumulationreflected the activity of the drug-induced pneumonitis. The present cases show very interestingFDG-PET imaging findings of diffuse lung disease.
