Application of ultrasound in aggressive angiomyxoma: Eight case reports and review of literature

Figure 1 Pathological results after H-E staining of one case.

Figure 2 Gray-scale ultrasonic images showing irregular hypoechoic masses with internal echogenicity and well-defined margins.

Figure 3 Internal blood flows in the mass detected by colour Doppler ultrasound.

Figure 4 Laminated or swirled appearance of inner echogenicity (blue arrows).

Figure 5 The finger-like growth pattern in the border of the mass could be demonstrated in both cases (blue arrows).

Figure 6 Magnetic resonance imaging images of case 4. A: Intermediate-intensity signals on TI-weighted sequence; B: Intermediate to high-intensity signals on T2-weighted sequence; C: Rapid and uneven enhancement pattern was shown after the injection of contrast agent.
