[Dural arteriovenous fistula of the lateral sinus: origin of objective tinnitus]. / Fístula arteriovenosa dural del seno lateral: origen de acúfenos objetivos.

ABSTRACT

Objective tinnitus usually has a vascular origin, but dural arteriovenous fistulas are rarely the cause of this sign. We report a case of arteriovenous meningeal fistula (AVMF) of the lateral sinus, origin of pulsatile objective tinnitus. Etiology, pathophysiology, symptoms, diagnosis, differential diagnosis and treatment of these fistulas are reviewed.
