Thrombosis of the deep cerebral venous system in the absence of superficial sinus thrombosis is a very rare disease. The clinical and radiological findings can be diagnostically challenging due to the subtle appearances on computed tomography (CT) scan. Magnetic resonance imaging (MRI) examination is a preferred imaging modality to complement the CT findings for an accurate diagnosis of venous ...

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...

BACKGROUND AND PURPOSE The diagnosis of dural sinus thrombosis is often difficult because of its variable and nonspecific clinical presentation and the overlapping signal intensities of thrombosis and venous flow on conventional MR images and MR venograms. We compared 3D contrast-enhanced magnetization-prepared rapid gradient-echo (MP-RAGE) sequences with 2D time-of-flight (TOF) MR venography, ...

Dural venous sinus thrombosis (DVST) in the neonatal period has a spectrum of clinical and radiologic findings. At the present time, the treatment for venous sinus thrombosis is mainly one of supportive therapy. In a patient with documented DVST, whose clinical status is deteriorating despite conventional supportive therapy, there may be a rationale for more aggressive therapy. We report a case...

chronic venous thromboses were also more common than acute thrombosis. Squizzato et al.1 reported 13 cases of acute cerebral sinus venous thrombosis associated with thyroid disease. The most common etiology of hyperthyroidism was Graves--Basedow disease, and a hypercoagulability state and even vascular compression in the event of large goiter were suggested as a pathogenetic mechanism. In the r...

Cerebral sinus venous thrombosis is an uncommon cause of stroke. Three factors usually predispose to venous thrombosis: hypercoagulability states, venous stasis, and blood vessel wall changes.1--3 In patients with thyrotoxicosis, the increased activity of factor VIII,4 amongst others, results in a hypercoagulability state and has been reported as being a factor which predisposes to cerebral sin...

A 34 year old man developed fever, right ear pain, and diffuse pulsatile headache 10 days prior to admission. Five days later he noticed difficulty in walking, instability, and intention tremor. Neurological examination showed a wide base gait, stance instability, slurred speech, bilateral horizontal nystagmus, intention tremor, four limb dysmetria, and dysdiadochokinesia. There were no signs o...

PURPOSE In autopsy reports of patients who died of septic cavernous sinus thrombosis, tributary venosinus occlusion has been a common finding related to intracranial inflammatory complications. The purpose of this article is to illustrate the MR and CT appearance of septic cavernous sinus thrombosis and tributary venous occlusion. METHODS Over a period of 7 years, eight patients with septic c...

Investigators from the Children's Hospital of Philadelphia analyzed the clinical and radiographic findings in 12 cases of cavernous sinus thrombosis (CST) seen between 2000 and 2013, and conducted a literature search and review of the pooled data.

Cerebral venous sinus thrombosis (CVST) and posterior reversible encephalopathy syndrome (PRES) are two rare diseases which may present with similar symptoms and signs. We report a case with coexisting PRES and CVST in a 34 years old postpartum female presented with multiple episodes of generalized seizures and bilateral vision loss after delivery. MRI brain and venography revealed left transve...
