Cerebral sinus thrombosis is a rare disease appearing mostly in young women. Typical symptoms include headache, convulsions, visual deterioration and various symptoms of neurological deficits. Magnetic resonance imaging of the brain and venous sinuses is the diagnostic cornerstone, whereby an obstructed venous sinus, thrombus mass and potential intracerebral lesions such as venous infarction or hemorrhage are diagnosed. Anticoagulant therapy should be initiated immediately once the diagnosis is confirmed.

Indications for brain imaging include potentially treatable intracranial causes (e.g. normal-pressure hydrocephalus, tumors, subdural hematoma) and especially characteristic features of memory disorders and differential diagnostics of such conditions. Since the primary structural changes in the most common progressive memory disorder, Alzheimer's disease, are seen in the inner temporal lobe, appropriate imaging of these structures is essential in early diagnosis.
