Materials and methods. The observation is introduced from clinical practice, exam-ination was performed on 1.5 Tesla MRI scanner with the acquisition of four regions of inter-est: head and neck, thorax, abdomen, pelvis and upper thigh. Scanning protocol included diffusion-weighted imaging sequence. Results. The examination has let us exclude the presence of the active tumor tissue in breast cancer patient after systemic neoadjuvant treatment and drew our attention to false positive PET/CT result, which in turn led to change of further treatment strategy. Conclusions. Interpretation of FDG-PET/CT should be done in a complex manner with clinical, laboratory and radiological data correlation.
