Magnetic resonance imaging findings of radiation-induced breast angiosarcoma: A case report

Figure 1 A skin ecchymotic plaque around the surgical scar on the right breast.

Figure 2 Mammography and ultrasound findings. A: The mammography (medio-lateral oblique view) showed dystrophic calcifications in the upper hemisphere and diffuse skin thickening, misdiagnosed as post-operative changes initially; B: The B-mode ultrasound showed non-specific findings except skin thickenings.

Figure 3 Illustrates the findings from contrast-enhanced breast magnetic resonance imaging, revealing diffuse skin thickening and nodularity. A: Presurgical breast magnetic resonance imaging depicts diffuse skin thickening with hyperintensity on T2-weighted images; B: Diffuse skin thickening is observed on T1-weighted images; C: Diffuse skin thickening enhances on the maximum-intensity projection of postcontrast dynamic images; D: The enhancement kinetics of cutaneous lesions show fast wash-in and wash-out (type 3 curve); E: The axial diffusion-weighted image exhibits hyperintensity; F: The corresponding apparent diffusion coefficient map shows hyperintensity, indicating diffuse vasogenic edematous changes in the skin.
