Cerebral venous sinus thrombosis (CVST) is an uncommon cause of cerebral infarction, compared to arterial diseases. It is often unrecognized at initial presentation due to the diversity of causes and clinical manifestations. A 29-year-old female patient complained of severe headache and presented at the emergency room with altered consciousness. Brain computed tomography and brain magnetic reso...

Cerebral venous sinus thrombosis can present with a variety of clinical symptoms ranging from isolated headache to deep coma. Subarachnoid haemorrhage is a rare presentation. In the report, we describe a case of non-puerperal venous thrombosis of many dural sinuses manifesting on imaging solely as localized subarachnoid haemorrhage without underlying parenchymal involvement.

There has been substantial emphasis placed on categorizing recanalization and collateral formation in patients with acute arterial occlusion resulting in ischemic stroke. Such methods of semi-quantitatively classifying the severity of arterial occlusion for prognostic purposes and assessing the response to treatment have become an integral part of clinical studies. However, no such method exist...

CLINICAL FEATURES The presentation of CVT can be acute, subacute or chronic. The presenting symptoms are grouped into four major syndromes (Bousser et al. 1997): • isolated intracranial hypertension – headache, visual obscurations, vomiting, papilloedema ± sixth nerve palsy (Biousse et al. 1999); • focal syndrome – focal or generalized seizure and/or a focal defi cit such as monoor hemi-paresis...

background: septic intracranial venous thrombosis is a rare vascular disease of the brain with no specific sign or symptom. while urgent treatment will result in complete recovery, delays may cause permanent complications or even death. case report: the patient was a 23-year-old woman who had suffered visual loss, hallucination, and confusion two weeks after undergoing submandibular abscess rem...

Cerebral venous sinus thrombosis is a disorder with a unique pathophysiology which needs to be described.A Medline search of all articles detailing pathophysiology of CVST was done, using keywords: cerebral venous thrombosis and pathophysiology. In addition, major texts were reviewed for additional references. The pathophysiology of CVST depends on two interconnected events, local signs due to ...

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...

A 65-year-old woman with poorly controlled diabetes presented bilateral miosis, bilateral abducens nerve palsy, and left hemiparesis. On MRI, cavernous sinus thrombosis, subdural empyema and hemorrhagic infarction in the frontotemporal lobe were detected. Cerebral angiogram revealed filling defect in the cavernous sinus with venous congestion but no involvement of internal carotid artery. Postm...

A 43-year-old woman, presented with headache, reduced visual acuity, for 5 days and bilateral papilledema. Non-enhanced cerebral computed tomography (CT) was normal. The venous angiography-CT revealed the empty delta sign within superior sagittal, right transverse and sigmoid sinuses, characterizing sinus thrombosis (Figure). The empty delta sign is a central intraluminal filling defect, repres...
