Pelvic examination and transvaginal ultrasonography were normal (Figure 1(a)), while color Doppler showed normal blood flow. MRI revealed normal uterine size, with a long axis of 80.6 mm, a short axis of 41.0 mm, and a width of 51.6 mm; however, the JZE thickness was 8.4 mm (Figure 1(b)).

PRL, and E2 levels were normal. Pelvic examination or ultrasonography likewise showed a normal uterus (Figure 2(a)), and color Doppler revealed normal blood flow. JZE thickness was 9.4 mm (Figure 2(b)). JZE thickening was not evident on MRI before surgery for submucosal fibroids, and no uterine fibroma or adenomyosis was observed.

Pelvic examination and ultrasonography showed a normal uterus (Figure 3(a)), and color Doppler showed normal blood flow. MRI also revealed a normal uterus, with a long axis of 86.8 mm, short axis of 51.3 mm, and width of 52.5 mm; however, the JZE thickness was 12.3 mm (Figure 3(b)).
