Fig. 1A70-year-old woman with history of treated ipsilateral breast
cancer and suspicious enhancement in lateral aspect of breast. Biopsy revealed
intracystic papilloma. MR image shows suspicious lesion (arrowhead)
and MRI skin marker (arrow). Posterior margin of biopsy grid is
indicated by thin white line.
Fig. 1B70-year-old woman with history of treated ipsilateral breast
cancer and suspicious enhancement in lateral aspect of breast. Biopsy revealed
intracystic papilloma. CT image obtained immediately after MRI shows lesion
(arrowhead) is close to MRI skin marker (arrow).
Fig. 2A45-year-old woman with suspicious enhancement adjacent to
breast implant. Pathology revealed benign breast tissue. MR image of
suspicious lesion (arrowhead) and retropectoral breast implant
(asterisk). MR-guided core needle biopsy could not be performed
safely because projected path of biopsy needle (dotted line) would
likely have ruptured implant. This image is rotated for comparison with
B.
Fig. 2B45-year-old woman with suspicious enhancement adjacent to
breast implant. Pathology revealed benign breast tissue. CT image shows lesion
(arrowhead) and retropectoral breast implant (asterisk) with
minimally radiopaque obturator in place (arrow).
Fig. 3B54-year-old woman with suspicious enhancement adjacent to
chest wall. Pathology revealed invasive ductal carcinoma and ductal carcinoma
in situ. After CT-guided placement of guide needle (arrow), lesion
(arrowhead) is faintly visible on sonography.
