Fig. 1From: Preexisting radiological interstitial lung abnormalities are a risk factor for severe radiation pneumonitis in patients with small-cell lung cancer after thoracic radiation therapyA 75-year-old male with small-cell lung cancer having preexisting radiological ILAs who developed RP beyond radiation field after TRT. a Prior to RT, initial HRCT exhibited subpleural reticular opacities at levels of bilateral lower lobes. b 60 Gy in 30 fractions was delivered to a pulmonary tumor in the right upper lobe with mediastinum and right hilar lymphadenopathy. Three weeks after completing RT, the patient developed diffuse interstitial infiltration and consolidation extending beyond radiation fieldBack to article page
