Clinical, mammographic and ultrasonographic features of blunt breast trauma

Evaluation of acute breast injury depends largely on the findings at physical examination. Patients may not initially remember the traumatic event to the breast, and mammography may be the first radiographic study to suggest this history, particularly if it shows findings of fat necrosis. Clinical, mammographic and sonographic findings resulting from non-iatrogenic trauma to the breast can be mistaken for signs of malignancy, especially because trauma often is not considered as a cause for such findings. In this paper some of the manifestations of blunt traumatic injury to the breast are presented. Familiarity with mammographic and sonographic findings of breast trauma is essential for the radiologist to avoid unnecessary biopsy and to avoid overlooking breast cancer.
