A rare case of venous sinus thrombosis and pulmonary embolisms secondary to myomatous erythrocytosis syndrome

Abstract

Myomatous erythrocytosis syndrome is a rare phenomenon of secondary polycythemia evolving from uterine leiomyoma. Although the underlying pathology is still unknown, patients have an increased risk of venous thrombosis. A 44-year-old GO (gravida zero) presented with an incidental finding of secondary polycythemia, and a diagnosis of myomatous erythrocytosis syndrome was made because of her large uterine fibroids. She was placed on therapeutic anticoagulation after developing pulmonary embolisms and a dural sinus venous thrombosis. Subsequently, she underwent uterine artery embolization, which resulted in a substantial decrease in her erythropoietin (8.1 mU/mL) along with hemoglobin (15.1 g/dL) and hematocrit (4 5g/dL). Myomatous erythrocytosis syndrome can cause venous thrombosis, leading to neurologic complications. In patients with increased risk for surgery, uterine artery embolization is an effective option for treatment.
