Cerebral venous sinus thrombosis in the setting of combined vaginal contraception.

We present a case of a 27-year-old women admitted to the hospital with migraine and left upper extremity weakness. Subsequent imaging with computed tomography and magnetic resonance angiography/venography demonstrated an acute-appearing central venous sinus thrombosis. Her only risk factor for venous thromboembolism (VTE) was the use of etonogestrel/ethinyl estradiol vaginal contraceptive ring (NuvaRing). The contraceptive ring was removed and the patient was treated according to the current guidelines. She achieved full neurologic recovery at 6 months' follow-up. Here, we describe this unusual case and review the risk of VTE between combined vaginal contraception and combined oral contraception.
