Radiology Imaging

Images in a 55-year-old woman with a spiculated mass localized in the upper central quadrant (arrow in A, B, D, and E) of right breast detected with digital breast tomosynthesis (DBT) plus synthetic mammography (SM). Breast density was classified as category C with the Breast Imaging Reporting and Data System. Mass was invasive ductal carcinoma, stage I, and was estrogen and progesterone receptor positive and human epidermal growth factor receptor 2 negative. A, Image from SM in craniocaudal view. B, Single-slice DBT image in craniocaudal view. C, Magnification of the lesion depicted in B. D, Image from SM in mediolateral oblique view. E, Single-slice DBT image in mediolateral oblique view. F, Magnification of the lesion depicted in E. Images courtesy of Radiological Society of North America

Enhanced axial CT (A) shows diffuse pleural thickening (arrow) with a maximum thickness of 3.17 mm. US image for the corresponding lesion on CT (B) shows diffuse pleural thickening (arrowheads) with a maximum thickness of 3.25 mm. The needle pathway length, measured as the needle length through the pleural lesion, was 6.54 mm (asterisk). Pleural puncture angle (exact value not indicated) is depicted as the angle between the outer line of the pleura and the biopsy needle (thin arrow).
