At physical examination, she had a soft swelling nodule, with two bluish-purple dots, in the umbilicus with a diameter of 1.2 cm, with a normal skin envelope, that was irreductible (Figure 2).
MRI: T2-weighted imaging. (a) Coronal view. (b) Axial view: uterus with multiple small nodules regarded as leiomyomas and with some endometrial glands suggesting adenomyosis.

Magnetic resonance imaging (MRI) showed uterus measuring 92 x 40 x 58 mm, with multiple small nodules showing signal hypointensity on T2-weighted imaging regarded as intramural leiomyomas and the presence of some endometrial glands suggesting adenomyosis, endometrium with 6 mm (Figure 3).

MRI also revealed a left septated ovarian cyst measuring 40 x 33 mm and a second cyst of 28 x 18 x 24 mm, containing fluid showing signal hyperintensity on T1-weighted imaging and slightly signal hyperintensity on T2-weighted imaging, suggesting hemorrhagic cyst or endometrioma (Figure 4).
