title: Stellate images: anatomic and radiologic correlations.
abstract: The stellate images are the most well-known and most typical finding in the diagnosis of breast cancer. Its positive predictive value is very high. However, in some cases, the stellate images can correspond to benign lesions. Stellate images require high quality mammograms, precise analysis, and as always in senology, confirmation by clinical examination, ultrasound if necessary, and in the case of palpable lesions, cytology. In this work, we will study malignant and benign stellate images mammographic-pathologic correlation as well as the importance of stellate images in the detection of non-palpable lesions. The typical stellate finding is correlated with the phenomena of fibrosis and elastosis and it is impossible to distinguish benign spicules from malignant spicules on mammography. We will present guidelines in the face of stellate image. Stellate images are for the most part suggestive of malignant lesions, and their discovery should lead to suspicion of cancer until the contrary is proven.
