Magnetic resonance images before uterine artery embolization. (a) T2-weighted axial image demonstrates a large intramural fibroid. The central area has a high intensity, suggesting degeneration. The asterisk (*) shows another degenerative uterine fibroid. (b) T2-weighted sagittal image demonstrates the endometrium (white arrow) compressed by the fibroid. The distance between the endometrium (white arrow) and the fibroid is very short. The asterisk (*) shows another degenerative uterine fibroid.

On T2-weighted image (T2WI), the fibroid had a homogeneously low signal and was present in close proximity to the endometrium (Figure 1).
Digital subtraction angiography images. (a) Pre-embolization aortography demonstrates hypertrophic uterine arteries and staining of the fibroid. (b) Post-embolization aortography demonstrates stasis in the uterine arteries bilaterally.

Ltd., Tokyo, Japan) to confirm staining of the uterine fibroid (Figure 2(a)). After embolization, we confirmed disappearance of staining of the fibroid (Figure 2(b)).
Magnetic resonance images 1 month after uterine artery embolization. (a) T2-weighted axial image demonstrates the fibroid protruding from the endometrium into the endometrial cavity (white arrows). The asterisk (*) shows another degenerative uterine fibroid. (b) T2-weighted sagittal image demonstrates prolapse of the fibroid into the internal os (white arrow). A small portion of the fibroid is protruding into the uterine cavity.

At 1 month after UAE, routine MRI showed that the fibroid shrunk to 95 x 75 x 70 mm; however, it was protruding into the cervical canal beyond the endometrium (Figure 3).
Magnetic resonance image 7 months following uterine artery embolization. T2-weighted axial image demonstrates a residual fibroid (white arrow) in the myometrium. The irregularity of the endometrium adjacent to the fibroid is shown. The asterisk (*) shows another degenerative uterine fibroid.

MRI showed a small residual fibroid remaining in the uterus after fibroid expulsion and the irregularity of the endometrium (Figure 4). Mild menorrhagia was still present; however, it was well controlled with hormone treatment.
Magnetic resonance image 11 months following uterine artery embolization. T2-weighted axial image demonstrates further shrinkage of the residual fibroid (white arrow) and improvement of the endometrial irregularity. The asterisk (*) shows another degenerative uterine fibroid.
