Objectives: To study the prevalence of intracranial venous stenosis in pseudotumor cerebri patients.
Patients & Methods: Thirty patients were diagnosed having PTC according to Dandy criteria. All underwent general and
neurological assessment. Radiological assessment included CT scan brain ?MRI brain without contrast, MRV. All underwent
digital subtraction angiography (DSA) (venous phase) to confirm the validity of filling gaps seen at the level of MRV.
Results: MRV brain showed that 24 patients (80%) showed filling gaps. Digital subtraction cerebral angiography (venous
phase) showed 9 patients (30%) had stenosis in their dural sinuses. MRV showed to be a good screening tool since it had 100%
sensitivity and negative predictive value. However, since it has a moderate specificity (62%) with a positive predictive value
(PPV) of only 35%, then lesions detected should be confirmed with digital subtraction cerebral angiography (venous phase)
particularly those involving the transverse and sigmoid sinus.
Conclusion: Studying the intracranial venous system in patients with PTC is an important step in understanding the
pathophysiology of the disease. Detection of venous sinus stenosis opens the way to a novel therapeutic option for refractory
patients like venous sinus stenting.
