State of the venous system in patients with Pseudotumor cerebri

Abstract

The article describes two clinical cases of idiopathic intracranial hypertension, the first manifestation of which was the development of retroorbital headache and the visual disorders. Leading in the clinical picture of the disease in both cases was the detection of stagnant optic nerve discs on the fundus. In both patients, the vascular system of the brain was examined using duplex scanning of the neck and brain vessels, MR angiography and MR venography, and in one case — SCT angiography, a lumbar puncture was performed with the study of cerebrospinal fluid (CSF). An increase in CSF pressure was found, accompanied by changes in the large venous vessels of the skull and brain. This suggests a significant role of venous outflow disorders in the development of Pseudotumor cerebri syndrome.
