title: Hypothalamic hamartoma associated with dural arteriovenous fistula of the transverse-sigmoid sinus--case report.
abstract: A 32-year-old female presented with a hypothalamic hamartoma associated with a dural arteriovenous fistula (DAVF) of the left transverse-sigmoid sinus. She complained of pulsatile tinnitus in the left retroauricular region and infertility. Endocrinological examination revealed that the luteinizing hormone reaction to luteinizing hormone-releasing hormone was exceedingly high. Magnetic resonance imaging demonstrated a distinct mass occupying the suprasellar cistern and protruding into the third ventricle. Left carotid angiography demonstrated a DAVF of the left transverse-sigmoid sinus, which was treated by embolization. Histological examination of a biopsy specimen of the tumor revealed a hamartoma. She was free from pulsatile tinnitus after treatment for the DAVF.
