Fig. 8. 63-year-old female with IDC in both breast and atelectasis mimicking pleural metastasis.

A, B. CE T1-weighted-MRI shows two IDCs, one on each breast (arrows), of approximately 1.7 cm and 1 cm.

C, D. CE T1-weighted-MRI shows an enhancing lesion in right superior diaphragmatic area of approximately 1.3 cm in size, mimicking pleural metastasis on the MRI. However, this lesion is correlated with right middle lobe atelectasis on the axial chest CT (arrows).

CE = contrast-enhanced, IDC = invasive ductal carcinoma
