Cerebral venous sinus thrombosis is a challenging condition because of its variability of clinical symptoms and signs. It is very often unrecognised at initial presentation. All age groups can be affected. Large sinuses such as the superior sagittal sinus are most frequently involved. Extensive collateral circulation within the cerebral venous system allows for a significant degree of compensation in the early stages of thrombus formation. Systemic inflammatory diseases and inherited as well as acquired coagulation disorders are frequent causes, although in up to 30% of cases no underlying cause can be identified. The oral contraceptive pill appears to be an important additional risk factor. The spectrum of clinical presentations ranges from headache with papilloedema to focal deficit, seizures and coma. Magnetic resonance imaging with venography is the investigation of choice; computed tomography alone will miss a significant number of cases. It has now been conclusively shown that intravenous heparin is the first-line treatment for cerebral venous sinus thrombosis because of its efficacy, safety and feasability. Local thrombolysis may be indicated in cases of deterioration, despite adequate heparinisation. This should be followed by oral anticoagulation for 3-6 months. The prognosis of cerebral venous sinus thrombosis is generally favourable. A high index of clinical suspicion is needed to diagnose this uncommon condition so that appropriate treatment can be initiated.

Cerebral venous sinus thrombosis is a rare, serious cerebrovascular disease with poor prognosis. It can be a sequel to various coagulation disturbances, head injuries or local inflammations. We report a case of a young woman with no risk factors detected, who developed a massive cerebral venous sinus thrombosis. She had progressively worsening symptoms, including left hemiplegia, aphasia, tonic-clonic seizures and unconsciousness. The diagnosis was supported by CT, MRI and angio-MRI findings. The intensive i.v. heparin and streptokinase treatment, as well as antibiotics, resulted in full remission of all patient's symptoms. The case emphasizes the necessity of early diagnosis and management of cerebral venous sinus thrombosis.

Cerebral venous sinus thrombosis (CVST) can present with a headache similar to that after a dural puncture. We report on a patient who developed postural headache after epidural anesthesia for delivery. The headache became more intense during the following 6 days, and the patient had a tonic clonic seizure. A magnetic resonance angiogram demonstrated CSVT, and anticoagulation therapy was started, with resolution of the symptoms over 2 wk. Any postdural-puncture headache that loses its positional character, becomes persistent, or does not improve with a properly performed blood patch should raise the suspicion of CVST.

Cerebral venous sinus thrombosis (CVST) is a rare and potentially deadly condition. Common etiologies include hypercoagulable diseases, low flow states, dehydration, adjacent infectious processes, oral contraceptives, hormonal replacement therapy, pregnancy, and puerperium. Symptoms include nausea, seizures, severe focal neurological deficits, coma, and headache (the most common presenting symptom). Anticoagulation is the mainstay of treatment for CVST. Transvenous clot lysis can be performed using injected thrombolytic agents and specialized catheters for clot retrieval.

Cerebral venous sinus thrombosis has been reported to be associated with various systemic illnesses and infections, including severe malaria. We report here a 43 year-old Thai male presenting with fever and seizures. He was diagnosed as and treated for severe falciparum malaria. After gaining consciousness he developed focal neurological signs and evidence of increased intracranial pressure. Magnetic resonance imaging (MRI) and magnetic resonance venography (MRV) of the brain revealed a mid-superior sagittal sinus thrombosis with venous infarction. Investigations for other infections and thrombophilia were negative. The patient denied anticoagulant treatment. The clinical status and radiologic findings improved gradually. Physicians who care for malaria patients need to be aware of this rare complication when a malaria patient presents with focal neurological signs.

Cerebral venous sinus thrombosis, an unusual presentation of antiphospholipid syndrome, is a rare condition in pregnancy, particularly in the first trimester. The authors of this case report present the case of a 20-year-old woman with sudden onset of headaches and hemiparesis in the first trimester of pregnancy. She underwent a computed tomography scan and magnetic resonance imaging. The image findings and the autoimmune serum test were consistent with a cerebral venous sinus thrombosis complicated by primary antiphospholipid syndrome. The patient's hemiparesis improved with subcutaneous low molecular weight heparin and oral aspirin. In the third trimester of pregnancy, she developed seizures that were controlled by antiepileptic drugs. She delivered a healthy baby at 37 weeks' gestation without immediate or late postpartum complications.

Cerebral venous sinus thrombosis caused by paroxysmal nocturnal hemoglobinuria is uncommon. Our case is a 44-year-old woman who presented with a 2 day history of headaches, nausea, and seizures followed by a Todd`s paresis; she had been diagnosed as paroxysmal nocturnal hemoglobinuria for 4 years. A magnetic resonance venography revealed extensive thrombosis of the cerebral venous sinus. She received antithrombotic treatment with a good outcome. We highlight paroxysmal nocturnal hemoglobinuria as the reason for the cerebral venous sinus thrombosis. The treatment of cerebral venous sinus thrombosis caused by paroxysmal nocturnal hemoglobinuria should be individualized.

Cerebral venous sinus thrombosis (CVST) during pregnancy and puerperium is an uncommon diagnosis. CVST can present with wide range of symptoms and signs, and most of the time it is left undiagnosed. Here, three cases of CVST in early pregnancy and puerperium in young women who presented with seizure attacks, altered sensorium and severe headache, respectively, are reported. Subsequent imaging with MRI and magnetic resonance venography (MRV) showed CVST in the first two cases, whereas in the third case it showed a venous infarction. All were treated with low molecular weight heparin followed by warfarin. They all made excellent recoveries and are in regular follow-up.

Cerebral venous sinus thrombosis in children is increasingly recognized as diagnostic tools and clinical awareness has improved. It is a multifactorial disease where prothrombotic risk factors and predisposing clinical conditions usually in combination constitute the underlying etiology. Clinical features range from headache, seizures to comatose state. Although symptomatic treatment involving control of infections, seizures and intracranial hypertension is uniform, use of anticoagulation and local thrombolytic therapy is still controversial. Morbidity and mortality can be significant and long-term neurological sequelae include developmental delay, sensorimotor and visual deficits and epilepsy.

Cerebral venous sinus thrombosis (CVST) is a rare cause of stroke, occurring when a blood clot forms in any of the brain venous sinuses. Symptoms include neurological deficits, headache, seizures, and coma. There are many predisposing factors for CVST including prothrombotic conditions, oral contraceptives, pregnancy/puerperium, malignancy, infection, and head injury. Cerebral venous sinus thrombosis has no identifiable underlying etiology in about 12.5% to 33% of the cases. Diagnosis has become easier with newer imaging techniques, such as magnetic resonance venography. The treatment options for CVST include symptomatic treatment, anticoagulation (AC), thrombolysis, and thrombectomy. Controversy exists over the efficacy and safety of AC in patients with CVST with concurrent intracranial hemorrhage (ICH). We present a complex case of CVST with ICH and mastoiditis as well as provide a literature review about CVST.
