Organizing pneumonia radiological evolution Case 9, Table 2; (a) CT scan at 2 months before the start of stereotactic body radiotherapy delivered by helical TomoTherapy (T-SBRT), the arrow indicates one of the two irradiated lesions; (b) CT scan at 4 months after the T-SBRT, the arrow shows a decrease in the volume of the lesion; (c) CT scan at 6 months (maximal extension of infiltrates) showing solid and ground-glass peripheral opacities that prevented the recognition of the malignant lesion; (d) CT at 9 months showing the substantial resolution of previous solid infiltrates and the development of other solid infiltrates in place of previous ground-glass opacities.
