Cerebral MR venography: normal anatomy and potential diagnostic pitfalls.
BACKGROUND AND PURPOSE MR venography is often used to examine the intracranial venous system, particularly in the evaluation of dural sinus thrombosis. The purpose of this study was to evaluate the use of MR venography in the depiction of the normal intracranial venous anatomy and its variants, to assess its potential pitfalls in the diagnosis of dural venous sinus thrombosis, and to compare th...
متن کاملSpontaneous Intracranial Hypotension Plus Cerebral Venous Thrombosis: A Case Report Study
This is a case study of a 34-year-old woman who was admitted to hospital with a history of severe orthostatic headache. She was diagnosed as having spontaneous intracranial hypotension (SIH) by undetectable cerebrospinal fluid (CSF) pressure at lumbar puncture, and with evidence of diffuse dural enhancement of the brain detected by magnetic resonance imaging (MRI). However, the contrast-enhance...
متن کاملPartially recanalized chronic dural sinus thrombosis: findings on MR imaging, time-of-flight MR venography, and contrast-enhanced MR venography.
BACKGROUND AND PURPOSE The imaging appearance of chronic, partially recanalized dural sinus thrombosis has been incompletely described. We sought to more fully characterize the imaging findings of this entity on MR imaging, time-of-flight MR venography (TOF-MRV), and elliptic centric-ordered contrast-enhanced MR venography (CE-MRV). MATERIALS AND METHODS From a data base of patients with cere...
متن کاملMR staging of acute dural sinus thrombosis: correlation with venous pressure measurements and implications for treatment and prognosis.
PURPOSE To correlate parenchymal brain changes, venous sinus pressure measurements, and outcome in 29 patients with acute dural sinus thrombosis. METHODS A retrospective review of 29 patients with angiographically proved acute dural sinus thrombosis was made from January 1989 to December 1993. MR examinations were performed on either a 0.5- or 1.5-T superconductive scanner in multiple planes....
متن کاملAnatomical Variations of Cerebral MR Venography: Is Gender Matter?
PURPOSE Knowledge of variations in the cerebral dural venous sinus anatomy seen on magnetic resonance (MR) venography is essential to avoid over-diagnosis of cerebral venous sinus thrombosis (CVST). Very limited data is available on gender difference of the cerebral dural venous sinus anatomy variations. MATERIALS AND METHODS A retrospective study was conducted to study the normal anatomy of ...
