Background: Intracranial dural arteriovenous fistulas (DAVF) are relatively rare vascular malformations. While the pathophysiology of their formation is unknown, they believed to be acquired lesions related intracranial venous hypertension and dura sinus thrombosis. There have been reports tumors associated with DAVF. Here we complete a systematic search literature. Methods: A PRISMA literature...

PURPOSE To identify the relationship between hemoglobin (Hgb) or hematocrit (Hct) level and dural sinus density using unenhanced computed tomography (UECT). MATERIALS AND METHODS Patients who were performed UECT and had records of a complete blood count within 24 hours from UECT were included (n=122). We measured the Hounsfield unit (HU) of the dural sinus at the right sigmoid sinus, left sig...

OBJECTIVES To show that mechanical compression of sigmoid sinus is effective for treatment of pulsatile tinnitus caused by sigmoid sinus enlargement, and to evaluate the relationship between the compression degree of sigmoid sinus and the tinnitus symptom relief using magnetic resonance angiography. METHODS Medical records of twenty-four patients who were diagnosed with venous tinnitus caused...

BACKGROUND AND PURPOSE Signs suggestive of unexpected dural venous sinus thrombosis are detectable on routine MR imaging studies without MRV. We assessed performance characteristics and interrater reliability of routine MR imaging for the diagnosis of dural venous sinus thrombosis, focusing on the superior sagittal, transverse, and sigmoid sinuses. MATERIALS AND METHODS This case series inclu...

On physical examination, she was tachycardic to 110 bpm, normotensive with a blood pressure of 108/64 mm Hg, and appeared uncomfortable. Neurological examination in the emerge...

Many cases of thrombosis of the sigmoid sinus, secondary to inflammation of the middle ear, have been successfully treated without ligature of the internal jugular vein. Some cases, indeed, have terminated favourably although neither the sinus itself nor the jugular vein have been directly treated. I have myself, in the practice of other surgeons, seen one case in which pyaemic abscesses formed...

Brucellosis is a commonly diagnosed zoonosis and neurological involvement is rare. A 30-year-old woman presented with a pulsatile headache that was exacerbated by the Valsalva maneuver and refractory to analgesic therapy. The patient also had nausea, cough, and coryza that evolved over 7 days. The neurological examination was unremarkable. Thrombosis of the lateral and sigmoid sinus and ipsilat...

This is a report of a case with unilateral cavernous sinus thrombosis due to ipsilateral ethmoid sinusitis. A 10 year old female was admitted in our hospital with severe headache, purulent postnasal discharge, right eye proptosis and third cranial nerve palsy in the same eye. She had history of viral upper respiratory tract infection and then acute otitis media which did not improve with rou...

UNLABELLED Otogenous lateral sinus thrombosis (OLST) is a rare disease and presents a controversial treatment. AIM Clinical aspects and treatment were reported based on our experience. METHODS Retrospective study. Six cases of OLST were treated in our institution in the last ten years. Clinical and imaging data were analyzed. RESULTS All six patients had the lateral sinus thrombosis detec...
