Extensive large tumour (white arrow) on sagittal TSE (a) and axial TSE (b) images (1.5 T). The tumour extends to several important structures (dotted arrows). After neo-adjuvant treatment, on TSE imaging (c, d) the tumor has shrunk considerably. The extension to nearby structures remains unaltered on the TSE image. Surgery therefore cannot be limited based on imaging after neo-adjuvant therapy
