Osimertinib‐induced pneumonitis usually manifests as ground glass opacities (GGO) on chest computed tomography (CT) scans. Here, we encountered a case involving a 42‐year‐old woman who had nodule‐type pneumonitis mimicking lung abscess or tumor recurrence caused by osimertinib. When a nodular pattern is seen on the chest CT scan of a patient receiving osimertinib treatment, drug‐induced pneumonitis should be considered as a differential diagnosis. To the best of our knowledge, this is the first case of osimertinib‐induced pneumonitis that manifested as a nodule‐type pneumonitis mimicking lung abscess or tumor recurrence on chest CT scan.
