What is the leading cause of morbidity and mortality in patients with polycythemia vera?
Venous and arterial thrombosis
The dural venous sinuses drain into which vein?
internal jugular vein
What thrombotic condition presents with signs/symptoms of increased intracranial pressure (seizures, headache, and other focal neurological deficits) and may lead to venous hemorrhage? This condition is classically associated with hypercoagulable states.
Venous sinus thrombosis
This abnormal MR venography of the brain suggests thrombosis of the right internal cerebral vein and thalamostriate branches which are not visualized as compared to the contralateral patent left internal cerebral vein and patent thalamostriate branches.
There is a component of chronic dural venous sinus thrombosis with non-visualization
of the straight sinus and inferior sagittal sinus as well as diminutive appearance of the left sigmoid sinus and transverse sinus.
