An 89-year-old woman had been prescribed oral warfarin for deep venous thrombosis. After an episode of cerebral hemorrhage, the warfarin was changed to oral edoxaban in consideration of the bleeding risk, and physical rehabilitation was continued in hospital. Two months later, she presented with a low-grade fever and oxygen desaturation. Her chest X-ray film and high-resolution CT revealed nonsegmental ground-glass opacities and the increase of lymphocyte count was shown in bronchoalveolar lavage fluid. Based on these findings, we diagnosed drug-induced pneumonia caused by edoxaban. Her respiratory condition and ground-glass opacities on CT improved with steroid pulse therapy. Although edoxaban-induced pneumonia has not been previously reported the possibility of drug-induced lung injury by edoxaban must be kept in mind.
