An ultrasound was performed for correlation with the initial ultrasound from 1 week ago, which was normal (not shown). Current ultrasound confirms a oedematous, enlarged left ovary (volume 54cc) with multiple small follicles and a corpus luteum displaced to the periphery. The vascular pedicle is also engorged, and there is a small amount of free fluid in the Pouch of Douglas.
Interestingly, arterial flow with normal waveforms was detected in both the ovary and its pedicle, suggesting either an incomplete torsion, or an element of torsion-detorsion.
