Transvaginal ultrasound scan.. Transvaginal ultrasound scan revealed absence of intrauterine gestational sac. A complex mass measuring 1.2 x 0.9 x 1 cm was seen (white arrow) close to the left ovary (LO) and was suspected to be a gestational sac at the left adnexa There was minimal fluid in the pouch of Douglas (arrow head) (A). Follow up transvaginal ultrasound 4 days later showed that the mass has increased in size (1.49 x 1.19 x 1.44 cm) (arrow heads) which contained a well-defined yolk sac (yellow arrow) (B).
