Awareness of primary spontaneous hemorrhagic angiosarcoma of the breast associated with Kasabach–Merritt syndrome in a pregnant woman by enhanced magnetic resonance imaging

Figures

  Figure 1. Axial T1-weighted image of MRI showing a large left breast mass with hyperintensity at the center and hypointensity at periphery, which can be due to central intra-tumoral hematoma. MRI = magnetic resonance imaging.

• 

  Figure 2. Axial T2-weighted image of MRI showing hyperintensity at the center and hypointensity at periphery, suggesting peripheral tumor location with central intratumoral hematoma. MRI = magnetic resonance imaging.

• 

  Figure 3. Axial enhanced T1-weighted image with fat suppression at early phase enhancement (1 minute after gadolinium injection) showing remarkable inhomogenously enhancement at the peripheral portion of tumor with nonenhancement at the center.

• 

  Figure 4. Axial enhanced T1-weighted image with fat suppression at delayed phase enhancement (5 minute after gadolinium injection) showing persistent pattern of tumor enhancement.

• 

  Figure 5. Histopathologic stud with microphotograph (2×) of excised angiosarcoma showing numerous anaestomotic vascular spaces and foci of malignant cells at the periphery of the tumor and hematoma at the center correlated the MRI features. MRI = magnetic resonance imaging.
