Heterotopic Pregnancy - Transvaginal ultrasonography revealed a 4-cm-by-4-cm right adnexal mass (Panel B, arrow) and intrauterine pregnancy (Panel C, arrow), as well as free fluid in the peritoneal cavity (Panel C, arrowhead), which caused concern about an ectopic pregnancy. An urgent laparoscopy was performed. On laparoscopy (Panel D), a ruptured ectopic pregnancy was seen in the right fallopian tube (arrowhead), and an intact gestational sac (white arrow) and embryo (black arrow) were also seen. #Clinical #Radiology #Heterotopic #HeterotopicPregnancy #US #NEJM
