A single intrauterine gestational sac is demonstrated, containing a single embryonic pole and yolk sac.
CRL 17mm ( 8 weeks 0 days).
Cardiac activity: Present, heart rate 162 bpm.
Perigestational haemorrhage present in the fundal region, measuring 39 x 17 x 20 mm (7 ml).
The gestational sac is centered in the lower uterine segment, with thickened decidua within the Caesarean scar nidus, and a thinned overlying myometrium, raising concern for a Caesarean scar implantation.
A corpus luteum is noted in the right ovary. 19 mm avascular echogenic lesion within the left ovary is in keeping with a dermoid cyst. This had been seen on prior studies.
