Purpose:
To assess the rate of jugular vein (JV) invasion by paragangliomas and imaging's ability to predict invasion.
Methods:
Imaging studies of patients with paragangliomas were evaluated for JV invasion. Rates of invasion by different paragangliomas and each modality's accuracy were determined.
Results:
JV invasion occurred in 11/11 glomus jugulares (GJs), 3/5 glomus vagales, and 2/8 carotid body tumors. Accuracy for magnetic resonance imaging (92.3%), computed tomography (92.3%), and digital subtraction angiography (94.1%) was comparable.
Conclusions:
JV invasion is characteristic of but not specific to GJs. All modalities show high accuracy in detecting invasion.
