Fatal pulmonary thromboembolism caused by idiopathic ovarian vein thrombosis

Ovarian vein thrombosis (OVT) is observed in the field of obstetrics and gynaecology. It is occasionally diagnosed during the postpartum period or in patients with ovarian malignancy. Few cases of pulmonary thromboembolism (PTE) caused by OVT have been reported previously. We report the case of a 67‐year‐old woman who presented with fatal PTE due to left OVT during hospitalization for cerebral infarction. The left ovary of the postmenopausal elderly patient showed no tumorous appearance. This case of OVT is extremely rare because of its idiopathic nature and fatal result.
