case_images: (a) B-mode endovaginal 2DUS showing a large irregular heterogeneous mass in the left pelvic abdominal region; (b) endovaginal 2DUS in power Doppler mode showing "ring" vascularization, indicative of a gestational sac. 2DUS: two-dimensional ultrasound.

case_images: This mass presented "ring" vascularization on power Doppler, indicative of a gestational sac (Figure 1).
case_images: (a) T2-weighted sagittal sequence MRI, showing uterus with 12-week conception in the anterior region and a complex mass occupying the retrouterine region; (b) adnexal T2-weighted sequence MRI, showing large cystic mass with "onionskin" appearance, which might correspond to multiple episodes of organized bleeding. MRI: magnetic resonance imaging.

case_images: A large left adnexal mass that probably had red blood cell content was observed, which measured 13 cm along its greatest diameter (Figure 2).
case_images: (a) Intraoperative situation, showing the presence of a great amount of coagulum in the pelvic cavity as well as lesions in the left uterine tube and ovary; (b) surgical specimen, showing left ovary with intact corpus luteum and small fragment of the left uterine tube.

case_images: A volume of 500 mL of coagulum came out from the left adnexa (Figure 3(a)). Left salpingooophorectomy was performed, and the resultant anatomopathological examination was conclusive for trophoblastic tissue (Figure 3(b)).
