The traditional view of thrombosis of the cerebral veins and/or sinuses (SVT) is that of a rare disease, difficult to diagnose, difficult to treat, and with a poor prognosis. Based on a number of recent findings, this concept has been revised. SVT is more frequent than previously thought but still rare compared with arterial stroke. Diagnosis is accomplished easily and in most cases noninvasively with new neuroimaging methods, however, the crucial first step towards the diagnosis is to think of it in the differential diagnosis of many clinical signs and symptoms. Many patients with SVT present with only minor neurological symptoms; however, if undiagnosed and untreated, the disease may progress to a state requiring intensive care (approximately 20% of cases).
