For higher sensitivity and specificity, these 3 imaging methods should be carried out together. Radiologists should be aware of the patient's history and complaints. Patients who have a specific history like a long-term drug treatment or a palpable tumour should be approached differently. Case Report: We would like to present 2 cases with atypical sonographic findings. The first case is an infiltrative breast cancer with occult sonography findings in a patient with a history of a long-term immunosuppressive drug treatment due to kidney transplantation and the second case is a malignant breast tumour which is hyperechogenic on sonography. Conclusions: Overall breast sonography should always be correlated with mammography in patients over 40 years old and the images should be interpreted along with the patient's history and clinical status.eninfo:eu-repo/semantics/openAccessBreastCarcinoma, Ductal, BreastUltrasonography, MammaryArticle43727822324N/A43481WOS:000386305700001N/A
