Hemorrhagic corpus luteum

Case contributed by Dr Alexandra Stanislavsky

Presentation

5 day history of right iliac fossa pain.

Patient Data

Age: 14 years
Gender: Female

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 hemorrhage.  This was favored 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.

Case Discussion

The two differential diagnoses in this case were an atypical appearance of a ruptured corpus luteum and ovarian torsion. 

A ruptured corpus luteum is the most likely cause for a moderate to large size pelvic hemorrhage in a non pregnant patient. Ovarian torsion however is by far the more critical diagnosis, therefore in this case a laparoscopy was performed to exclude this.
