BACKGROUND A comprehensive assessment of various vascular anomalies and variants associated with venous pulsatile tinnitus (PT) by radiography is essential for therapeutic planning and improving the clinical outcome. This study evaluated the incidence of various vascular anomalies and variants on the PT side and determined whether these lesions occurred as multiple or single entities. METHODS...

We report a case of hypoplasia of the right transverse sinus and aplasia of the ipsilateral sigmoid sinus and the internal jugular vein. In addition, development of the petrosquamosal sinus and the presence of a large middle meningeal sinus and sinus communicans were observed. A 53-year-old Caucasian woman was referred for magnetic resonance imaging (MRI) investigation due to chronic headache. ...

Objective: To observe the clinical manifestations, imaging features of a case of a patient with cholesteatomatous otitis media complicated with suppurative meningitis and venous sinus thrombosis and to explore the treatment method and prognosis. Method: The medical history of the patient and the data of physical examinations, imaging examinations and laboratory examinations were collected. Resu...

Cerebral venous sinus thrombosis (CVST) is a rare but serious disorder that is associated with a poor clinical outcome. We report a 35-year-old man who had a severe headache and diplopia while climbing Mount Everest. His MR venography showed right transverse and right sigmoid sinus thrombosis. He improved on anticoagulant and symptomatic measures. Cerebral venous sinus thrombosis at high altitu...

Dural sinus thrombosis (DST) usually involves the sagittal, transverse and sigmoid sinuses and is more common in women due to pregnancy, puerperium and oral contraceptive use. Other etiologies include coagulopathies, infection and head injury. We have present two DST cases following head injury. The first case was a 35-year-old man hospitalized because of one-week history of headache and repeat...

The venous efflux from cerebral dural venous sinus into the extracranial venous drainage is predominantly based on sigmoid venous sinus draining into the internal jugular vein. In the fetal stage, the rapid growth of cerebral hemispheres leads to an enlargement of transverse venous sinuses in somewhat disproportionate manner to growth of sigmoid venous sinus and internal jugular vein. Therefore...

A 20-year-old woman was admitted to a Gynecology Hospital in her 6(th) month of pregnancy for high blood pressure and tonic-clonic seizure. Primary diagnosis was eclampsia, and for that reason she underwent cesarean section. She also had headache on frontal and parietal areas without nausea or vomiting. There was not a focal neurological sign. Rheumatology consultation was requested. Systemic l...

413 Numerous factors may lead to pulsatile tinnitus (PT), including atherosclerosis, benign intracranial hypertension, glomus tympanicum tumor, dural arteriovenous fistulas (dAVFs), abnormalities of the sigmoid sinus (dehiscence and diverticulum), and jugular bulb anomalies (glomus jugular tumor, diverticulum, high‑riding or dehiscent jugular bulb). However, exact causes often cannot be found i...

The purpose of this study was to review our experience with a single case of mastoiditis associated with sigmoid sinus thrombosis and increased intracranial pressure, and to review the experience of others through prior publications. We reviewed a case of a 6-year-old boy with an acute otitis media and mastoiditis, with associated ipsilateral sigmoid sinus and contralateral distal transverse si...
