Pelvic Pain and Adnexal Mass: Be Aware of Accessory and Cavitated Uterine Mass

Figure 3

(a) Axial T2-weighted image of the pelvis shows a well-defined left-sided adnexal mass with signal intensity similar to the uterus (black arrow) with a central hypersignal endometrium (white arrow). (b) Axial contrast-enhanced fat-saturated T1-weighted image of the pelvis also demonstrates an enhancement similar to the uterus (black arrow). A right-sided simple ovarian cyst is also observed (asterisk). No pelvic lymphadenopathy is evident on magnetic resonance imaging.
