Breast Lesions on Chest Computed Tomography: Pictorial Review With Mammography and Ultrasound Correlation

This pictorial review demonstrates computed tomography (CT) features with mammogram and, in some instances, ultrasound and positron emission tomography scan correlation of a wide spectrum of both malignant and benign findings on breast evaluation. Characterization of the margins, shape, pattern of enhancement, density, and associated findings is essential for accurate assessment of breast lesions during CT examination. Spiculated margins, irregular shape, and the presence of enhancement have a high predictive pattern for malignancy. The associated findings that could be seen include skin thickening, lymphadenopathy, architectural distortion, or chest wall or skin invasion. Nearly all detected breast calcifications on chest CT scans are benign. However, any breast masses and calcifications seen need further evaluation by other modalities, such as mammography or ultrasound or both.
