ABSTRACT We report a case of atypical cerebral venous drainage in a 38-year-old woman with symptoms of benign paroxysmal positional vertigo. Thrombosis of the left internal jugular vein and sigmoid sinus was suspected on the basis of spin-echo and time-of-flight MR findings, but multisection CT angiograms showed a patent sigmoid sinus and predominant drainage via the emissary veins toward the vertebral plexus, with only a minor contribution of the jugular veins. This case illustrates the variability of the venous anatomy in the craniocervical region.

    ABSTRACT: Dural arteriovenous fistulas involving marginal sinus are relatively rare. Transvenous embolization is a curative treatment of choice for them. Regional anatomy surrounding the marginal sinus comprises complex craniocervical bony structures and abundant venous interconnections. Therefore, dural arteriovenous fistulas involving marginal sinus may have various routes for a transvenous approach. The purpose of this article was to analyze endovascular treatment of marginal sinus dural arteriovenous fistulas with emphasis on the routes of transvenous embolization. Five patients with dural arteriovenous fistulas (DAVFs) involving the marginal sinus who were treated with transvenous embolization were retrospectively analyzed in terms of endovascular treatment: angiographic architecture, routes of venous approach, and treatment results case by case. There were no significant complications except for headache, ocular pain, and facial flushing after transvenous embolization. Immediate angiographic outcomes were complete in four patients and partial in one patient. Clinical outcomes during follow-up were complete recovery in four patients and intermittent tinnitus in one patient. Three different transvenous approaches were used for transvenous coil embolization: ipsilateral internal jugular vein in three patients, contralateral internal jugular vein in one patient, and vertebral venous plexus in one patient. Transvenous coil embolization in treating marginal sinus DAVF is a safe and effective method. In case of failure of an internal jugular venous approach, alternative routes of embolization should be considered. Understanding the regional venous anatomy of the craniocervical junction is important for targeting fistulous sites and selecting routes for transvenous embolization.

    ABSTRACT: Although pulsatile tinnitus can be audible, objective demonstration of this heartbeat-synchronous sound has rarely been successful. We report a rare case of pulsatile tinnitus in a 44-yr-old female patient, which was induced by a large mastoid emissary vein (MEV) and objectively documented by Doppler sonography of the left posterior auricular region. The tinnitus was intermittent and the patient could adapt to the tinnitus without intervention on the mastoid emissary vein. These findings suggest that a single large MEV can cause pulsatile tinnitus in the absence of other vascular abnormalities, and imaging studies of the posterior fossa and Doppler ultrasonography can aid the diagnosis in such cases.
