Norethisterone Enanthate–Induced Cerebral Sino-Venous Thrombosis (CSVT)

Abstract

Cerebral sino-venous thrombosis is a potential life-threatening condition that requires rapid diagnosis and urgent treatment. The association between progestin-only pill used for the treatment of menstrual disorders and cerebral venous thrombosis has rarely been reported in the literature. We report a case of cerebral venous thrombosis following the intake of norethisterone for menorrhagia in a young woman. Although venous thrombosis is usually linked to the ingestion of estrogen, rather than progestogen, this case illustrates that patients who are prescribed progestogen-only pills for gynecological disorders may develop thrombosis.
