case_images: Abdominopelvic CT was performed to accurately locate the ectopic pregnancy, revealing a 3.3 cm cystic mass in the precaval area beneath the third segment of the duodenum, characterized by thick and intense peripheral enhancement (Fig. 1A, B). Upon accessing the abdominopelvic cavity, the site at which bilateral salpingectomy was performed became apparent, and a gestational sac was evident in the precaval area covered by the peritoneum (Fig. 1C). Subsequent pathological examination confirmed that the cystic mass consisted of chorionic villi (Fig. 1D).
