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...

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...

A 21 year college student came with a history of generalized tonic-clonic seizures. MR Venography revealed the presence of left sigmoid and transverse sinus thrombosis with secondary venous hemorrhagic infarcts. After thorough investigation into cause of thrombosis patient was found to have a heterozygous MTHFR A1298C mutation which was causing cerebral venous sinus thrombosis.

Although few patients with spontaneous intracranial hypotension develop cerebral venous thrombosis, the association between these two entities seems too common to be simply a coincidental finding. We describe two cases of spontaneous intracranial hypotension associated with cerebral venous thrombosis. In one case, extensive cerebral venous thrombosis involved the superior sagittal sinus and mul...

Introduction: Extreme altitude travel has gained popularity globally for adventurous, scientific, and military endeavors. Cerebral venous sinus thrombosis (CVST) at extreme altitude is a rare, covert, and emergent condition requiring immediate intervention. Case Presentation: A case of CVST masqueraded as high altitude cerebral edema (HACE) at 6700 m/22000 ft i...

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 ...

Radiographic signs of cavernous sinus thrombosis were found in eight consecutive patients with an angiographic diagnosis of carotid-cavernous sinus fistula; six were of the dural type and the ninth case was of a shunt from a cerebral hemisphere vascular malformation. Diagnostic features consisted of filling defects within the cavernous sinus and its tributaries, an abnormal shape of the caverno...

Background: Cerebral venous sinus thrombosis (sinovenous) (CSVT) is a rare and yet an important cause of morbidity and mortality in neonates. The Canadian registry quotes an incidence of 41 per 100,000 newborns per year. Cerebral sinovenous thrombosis is rarely reported in preterm infants. Although it is a potentially devastating condition with poor neuro developmental outcome, the risk factors...

Cerebral venous thrombosis is an uncommon, but important cause of stroke due to its high morbidity. Though conventional catheter based angiography is becoming replaced by newer, noninvasive imaging modalities, it still plays an important role in the evaluation of patients with suspected sinus or venous thrombosis. Techniques of angiography, normal anatomy and variants, and pathological drainage...
