Primary angiosarcoma of the breast: Two case reports and brief review of the literature

Figures

• 

  Fig. 1. The lesion was well-demarcated margin (A) and rich blood supply signal (B).

• 

  Fig. 2. The lesions were hyperintense on fat-suppressed T2WI (A) and isointense on fat-suppressed T1-weighted imaging (T1W1) (B). DCE-MRI demonstrated a rapid enhancement followed by a typical plateau pattern of the enhancement curve for the lesions of the bilateral breasts with well-demarcated margins and without the involvement of the skin and nipple (C-D). All masses shown slightly restricted diffusion on DWI (b = 1000 s/mm2) and ADC maps (E-F). The ADC values were 1.40 × 10−3mm2/s for the left lesion. Bilateral draining vessels (white arrows) were dominant on color maps of maximum intensity projection (MIP) images in axial view (G) and sagittal view (H). ADC, apparent diffusion coefficient; DWI, diffusion-weighted imaging.

  Fig. 3. The lesions on left breast presented with high signal intensity on T2WI (A) and low-intermediate signal intensity on T1WI (B). DCE-MRI shows a rapid inhomogeneous enhancement with a plateau pattern for lesion 1 (red circle) and a rapid inhomogeneous enhancement with a washout pattern for lesion 2 (green circle) (C-E). The lesions have slightly restricted diffusion on DWI (b = 1000 s/mm2) and ADC maps (F-I). The ADC values were 1.44 × 10−3mm2/s for lesion 1 and 1.48 × 10−3 mm2/s for lesion 2. Dominant draining veins (white arrows)around the lesions were observed on the color maps of maximum intensity projection (MIP) images in sagittal view (K). ADC, apparent diffusion coefficient; DWI, diffusion-weighted imaging.
