Ovarian vein thrombosis usually presents as fever and abdominal pain in postpartum or post-op patients. This case was unusual as the patient did not have an obstetric/surgical history. The cause was thought to be due to the patient ceasing the combined oral contraceptive pill 4 months ago and restarting it 2 weeks prior to presentation.

The patient was commenced on anticoagulation and referred for thrombophilia screening.
