From: CT patterns and serial CT Changes in lung Cancer patients post stereotactic body radiotherapy (SBRT)
SBRT-treated lung cancer demonstrates local recurrence at 35 months: a) Isodose multiplanar images for planning. b) Pre-SBRT CT shows a cavitary mass in the left upper lobe. c) 6 mo post-SBRT, the lesion decreased in size. d) 16 mo post-SBRT, the primary lesion is obscured by surrounding consolidation and mild GGO. e) 20 mo post-SBRT there is architectural distortion in keeping with “modified conventional pattern”. f) 30 and g) 36 mo post-SBRT, the radiation changes became denser and more well-defined retaining the “modified conventional pattern”
