Fig. 3.
A 49-year-old woman with glycogen-rich clear cell carcinoma (GRCC) in the left breast. (A) Mediolateral oblique view of mammography shows an oval, circumscribed hyperdense mass at the upper central quadrant of the left breast. (B) Ultrasonography reveals a thick-walled complex cystic and solid mass with circumscribed margin. (C) On T2-weighted MRI, the solid portion of the mass shows intermediate signal intensity and the cystic portion at the center shows high signal intensity. (D) Dynamic contrast-enhanced image with subtraction shows an oval, circumscribed mass with rim enhancement.
