Ovarian vein thrombosis (OVT) usually occurs on the right side in women with underlying conditions such as pelvic diseases and thrombophilia or during the postpartum period. Here, we present a patient with bilateral OVTs without underlying conditions. A 63-year-old woman without remarkable past or family histories complained of mild lower abdominal pain. Computed tomography revealed bilateral OVTs, with the right-sided thrombus nearly progressing into the inferior vena cava. The presence of symptoms and risk of thrombus extension/pulmonary embolism (PE) led us to administer an oral anticoagulant (rivaroxaban) promptly. Her symptom improved gradually and bilateral OVTs disappeared by 3 months without any evidence of PE. The present case suggests that OVT can occur in a woman without underlying conditions, and the use of an anticoagulant may be a treatment option in such a case.
