The "Hyperdense Paraspinal Vein" Sign: A Marker of CSF-Venous Fistula.
نویسندگان
چکیده
CSF-venous fistula is a recently reported cause of spontaneous intracranial hypotension that may occur in the absence of myelographic evidence of CSF leak. Information about this entity is currently very limited, but it is of potential importance given the large percentage of cases of spontaneous intracranial hypotension associated with negative myelography findings. We report 3 additional cases of CSF-venous fistula and describe the "hyperdense paraspinal vein" sign, which may aid in its detection.

Prevalence of hyperdense paraspinal vein sign in patients with spontaneous intracranial hypotension without dural CSF leak on standard CT myelography.
PURPOSE A recently identified and treatable cause of spontaneous intracranial hypotension (SIH) is cerebrospinal fluid (CSF)-venous fistula, and a recently described computed tomography myelogram (CTM) finding highly compatible with but not diagnostic of this entity is the hyperdense paraspinal vein sign. We aimed to retrospectively measure the prevalence of the hyperdense paraspinal vein sign ...

A paravertebral presacral posttraumatic arteriovenous fistula drained through the ascending lumbar vein to the epidural plexuses and perimedullary veins.

In the rare case of connection with the spinal venous system, they might affect spinal ...
