A venous-type flow in the intramural venous plexus, a turbulent aspect in the fistula, and a high-velocity low-resistance flow in the artery branch were observed in patients with AVM (Figure 1). A mass measuring 22 x 19 mm in size with abundant blood flow in the myometrium was shown on Doppler imaging as a mosaic color pattern (Figures 1 and 2).

A mass measuring 22 x 19 mm in size with abundant blood flow in the myometrium was shown on Doppler imaging as a mosaic color pattern (Figures 1 and 2).
AVM spontaneously regressed after 6 weeks without UAE (Patient 1).

Four weeks following diagnosis, the patient's estradiol level dropped to 5 pg/mL, the hCG level dropped to 4.9 mIU/mL, and the AVM disappeared (Figure 3).

After 1 week, the abnormal vessels had grown to a size of 16 x 6 mm with abundant blood flow, which was shown on Doppler as a mosaic color pattern (Figure 4).
