Morphometric Relationship of the Transverse Sinus with Sigmoid Sinus Groove and Jugular Foramen

Comparative morphometric study of the sigmoid sinus sulcus and the jugular foramen.

OBJECTIVE To compare the right and left sides of the same skulls as far as the described landmarks are concerned, and establish the craniometric differences between them. METHOD We carried out measurements in 50 adult dry human skulls comparing both sides. RESULTS The sigmoid sinus width at the sinodural angle level was larger on the right side in 78% of the cases and at the level of the di...

Aplasia of sigmoid sinus with high-lying jugular bulb.

A 25-year-o ld woman was admitted with a 20 year history of pulsatile tinnitus. She had been aware of " buzzing " in her right ear since she was a ch ild. There was no history of otalgia, hearing loss, nor ear discharge. Th e physical examination revealed a blue hypotympanic mass medial to an intact right tympanic membrane. Increasing the air pressure in the external canal failed to cause a bla...

Jugular Foramen Meningioma with Transverse and Sigmoid Sinuses Invasion and Jugular Vein Extension.

Transverse-sigmoid sinus dural arteriovenous fistula presenting with parkinsonism.

Dural arteriovenous fistula (DAVF) is rarely associated with parkinsonism. A 52-year-old woman presented with a rare case of DAVF manifesting as parkinsonism and subsequently akinetic mutism. She showed dramatic recovery after endovascular treatment. We also review 10 published reports of DAVF presenting with parkinsonism. The clinical features of these cases at presentation was more closely co...

Clinical syndromes of arteriovenous malformations of the transverse-sigmoid sinus.

Arteriovenous malformations or fistulae shunting arterial blood from branches of the external and internal carotid and vertebral arteries into the transverse-sigmoid sinus may produce different clinical syndromes. The literature is reviewed with 96 patients including six personal cases. Usually these malformations have a congenital origin and only in 4% of the series was there a previous histor...
