title: Objective pulsatile tinnitus caused by intrapetrous dissecting aneurysm.
abstract: Intrapetrosal dissections is a special kind of intracranial dissection since it is located intracranially but extradurally. Only three reports of spontaneous intrapetrosal dissection have been published so far, the posttraumatic intrapetrosal dissections caused by penetrating or blunt trauma not included. Based on the clinical and radiological presentation a treatment with anticoagulantia (a coumarine derivative) was successfully installed. A short review of the major studies concerning intracranial dissection is presented. Firm guidelines for the treatment cannot be provided based on these data but the etiology of the dissection, whether it was posttraumatic or spontaneous, seems to be important. The diagnostic problem of pulsatile tinnitus is briefly discussed.
