The Clinical Spectrum of Sinus Venous Thrombosis

The true incidence of sinus venous thrombosis (SVT) is unknown because many patients remain undiagnosed or are misdiagnosed. Unfortunately, the symptoms and clinical signs of SVT are unspecific and resemble those of other more common or better known neurological disorders such as ischemic stroke, meningitis, encephalitis, or subarachnoid hemorrhage (SAH). Furthermore, the gold standard in the diagnosis of SVT is cerebral angiography, an invasive method with considerable risk of severe side effects, which many physicians try to avoid in the diagnostic process.
