Figure 9c. Left breast cancer in a 66-year-old woman who had undergone MRM and irradiation. (a) Portal radiograph demonstrates a supraclavicular field. (b) Radiograph obtained 4 months following completion of radiation therapy shows ill-defined consolidation in the left apex (arrows). (c) CT scan shows ill-defined patchy consolidations in the left apex. (d) Follow-up chest radiograph shows some linear areas of increased opacity in the left apex (arrow), a finding that mimics tuberculous scar. (e) CT scan obtained 15 months later shows regression of the areas of increased opacity in d into a dense, bandlike fibrosis.
