A 56-year-old patient with ILC of the left breast received neoadjuvant chemotherapy. a Pre NAC mammogram CC view showing a left breast focal asymmetry. b Post NAC mammogram CC view showing reduction in size. c Pre NAC CESM CC view grouped enhancing lesions. d Post NAC CESM CC view showing no residual pathological enhancement. e Quantitative mathematical objective evaluation. RECIST 1.1 classified the patient as partial responder. Combined response evaluation classified this patient as a complete responder. Quantitative mathematical objective evaluation showed 99% regression. Pathological evaluation confirmed this patient as acomplete responder (Miller–Payne grade 5)
