The time-series of the deterioration of radiation pneumonitis in two cases. Grade 3 radiation pneumonitis developed two and three months after HT-SBRT in Case 1 and Case 2, respectively. Steroid administration resolved the symptoms and pulmonary inflammatory shadow, but the relapse of radiation pneumonitis occurred after steroid discontinuation or tapering, resulting in the lethal exacerbation of radiation pneumonitis 4 and 7 months after HT-SBRT in Cases 1 and 2, respectively (a: Case 1; b: Case 2).
