Abstract

Abstract : Supplemental digital content is available in the text. Abstract : Objective: The aim of the study was to retrospectively investigate the fat-saturated T2-weighted sequences (FST2WI) and 3-dimensional dynamic contrast-enhanced sequence (DCE) of magnetic resonance imaging (MRI) findings of breast spindle cell carcinoma (SpCC). Methods: Twenty-six women with surgically confirmed breast SpCC, who underwent breast MRI in 2 institutions, were enrolled in this study (mean age, 54 years; range, 27–81 years). Two breast radiologists determined the MRI findings by consensus after independent interpretations. Each MRI finding was analyzed. Results: Most lesions of SpCC showed a solitary mass (92.2%). Most masses were round/oval (76.0%), had an irregular margin (88.0%), rim enhancement (72.0%), washout kinetic analysis (96.0%), hyperintensity on FST2WI (84%), hyperintensity on FST2WI and fast enhancing component on DCE (56%), and hypointense rim on FST2WI (72.0%). Conclusions: Most breast SpCC showed a solitary mass, round/oval shape, irregular margin, rim enhancement, washout kinetics, and intratumoral hyperintensity on FST2WI; a hypointense rim on FST2WI; and hyperintensity on FST2WI and fast enhancing component on DCE.
