"Cerebral venous thrombosis pathogenesis remains poorly understood 5. There is an extensive list of known risk factors, already mentioned above."
"Noncontrast CT, when not associated with venous haemorrhage or infarction can be a subtle finding, relying on hyperdensity of the sinus being identified 1,5. Thrombus can appear as a hyperdense vein or sinus for the first 7-14 days; this is an accurate sign when present 6. The cashew nut sign, which describes small, concave, juxtacortical intracerebral haemorrhages, is specific for cerebral venous thrombosis when present 14."
