Ultrasound and mammography in the differential diagnosis of gynaecomastia

Ultrasound as well as mammography are the priority modalities in the differentiation of breast diseases in men, as they have an optimal ratio of efficiency to ease of investigation. In contrast to, for example, invasive histological examination, which is highly effective but traumatic. Or computed tomography, which has a high radiation load, because of which it is not possible to carry out studies to fix the dynamics of the disease. At the same time, studies of gynaecomastia show a high prevalence in the population, despite the fact that most men do not pay attention and do not know that they may have this pathology. Although this pathology is a significant risk factor for breast oncology. Therefore, the purpose of this review is to summarise the signs that you may see with these two instrumental examinations. They allow with a high degree of probability to allow you to make a tentative diagnosis. At the same time, often these studies together with physical examination methods are sufficient even for a definitive diagnosis, although the sensitivity and specificity of the methods do not reach 100% of the results. This leads to the fact that ultrasound and mammography can be used as the first line of diagnosis of gynaecomastia.
