Low-Grade Endometrial Stromal Sarcoma with a Nodule-in-Nodule Appearance in Preoperative Magnetic Resonance Images

Dynamic contrast-enhanced T1-WI pelvic MRI: (a) precontrast; (b) postcontrast 20 s; (c) postcontrast 60 s; (d) postcontrast 180 s. In dynamic contrast-enhanced T1-WI, the small nodules are enhanced rapidly and stronger than the normal myometrium in the early phase and decrease gradually in the later phase to the level similar to that of the normal myometrium. In contrast, the larger mass is enhanced gradually and heterogeneously, but it is weaker than the normal myometrium.
