Magnetic resonance venography in idiopathic pseudotumor cerebri.
OBJECTIVE
To inform clinicians about the use of magnetic resonance (MR) venography in idiopathic pseudotumor cerebri.


METHODS
A prospective study to evaluate for the presence or absence of dural sinus thrombosis using MR imaging and MR venography of the brain in 22 consecutive young, female, overweight patients with typical pseudotumor cerebri.


RESULTS
None of the 22 MR imaging and MR venography studies showed venous sinus thrombosis.


CONCLUSIONS
Magnetic resonance venography might not add significantly to the evaluation of typical idiopathic pseudotumor cerebri but may be indicated in atypical cases (e.g., male, thin, or elderly patients).
