The clinical manifestations of dural arteriovenous fistulas (dAVFs) are highly variable and dependent on the hemodynamic properties location fistula. locations fistula numerous include cavernous sinus, transverse–sigmoid superior sagittal inferior petrosal sinuses, anterior condylar confluence, tentorium, cranial fossa, middle foramen magnum, cranio-cervical junction, convexity, spinal cord. Th...

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 ...

A 14-year-old girl fell off a truck, striking her head. She lost consciousness for 7 minutes. Results of initial evaluation and computed tomography (CT) of the head appeared to be unremarkable on the day of her injury. Three days later, she presented with symptoms of increased ICP including persistent headaches, vomiting, and pulsatile tinnitus, as well as decreased hearing on the right. Head C...

Acute intracranial dural sinus thrombosis may have severe morbidity or fatal complications without appropriate treatment. Direct dural sinus venography can be performed safely with a soft Tracker catheter to document the fresh thrombus as an adjunct to CT or MR. We are reporting our experience with successful direct urokinase thrombolytic therapy in three cases of superior sagittal sinus and tw...

so that specific treatment can be started. The cord sign (hyperdense thrombosed veins on unenhanced CT) and the empty-delta sign (a filling defect in the superior sagittal sinus on enhanced CT) are considered pathognomonic for SVT.

BACKGROUND AND PURPOSE The dural venous sinuses in neonates differ from those in adults or older children in that the caliber of venous sinuses is smaller and there is skull molding. The aim of this retrospective study is to evaluate the presence of flow gaps in venous sinuses in neonates on 2D time-of-flight (TOF) MR venography (MRV). METHODS Fifty-one neonates underwent coronal 2D TOF MRV. ...

For 150 years, the variable clinical appearance of dural sinus thrombosis has plagued clinicians. Computed tomography (CT) has alleviated much of the difficulty in making this diagnosis. A high density lesion in the involved sinus on precontrast scans and a filling defect in the sinus on postcontrast scans were the most frequently observed CT abnormalities in 12 patients with sinus thrombosis. ...

Patients with dural arteriovenous fistulas (DAVFs) in the transverse-sigmoid sinus suffer from several symptoms: bruit, headache, visual impairment, and so on. But depression is rare in patients with DAVF. The authors reported a rare case presenting the improvement of depression after the treatment of a dural arteriovenous fistula in the left transverse-sigmoid sinus. A 46-year-old male had suf...
