Pathophysiology, histopathologic-imaging correlation.
Radial scar is one of the hyperplastic breast changes that can mimic breast cancer. Using tomosynthesis, radiologists are detecting an increasing number of radial scars, so it is important to know the underlying pathophysiology, correct terminology, differential diagnostic options and correct management. This lecture describes the multimodality approach to arriving at the correct diagnosis. In addition, the lecture also describes the seldom seen but important hyperplastic breast change, the so-called Swiss Cheese Disease. Clinical breast examination findings, imaging findings and management are detailed in this lecture.
