Transabdominal pelvic ultrasound demonstrates a moderate amount of pelvic free fluid. The right ovary is mildly enlarged, and contains a heterogeneous complex cystic area with some rim vascularity and internal low level echoes suggestive of haemorrhage. This was favoured to represent a corpus luteum associated with pelvic rupture. However, given the subacute timeframe and atypical appearance, a delayed presentation of ovarian torsion was strongly considered as a differential, and therefore a laparoscopy was performed.
