The condylar emissary veins (anterior, lateral, posterior) are major posterior cranial fossa emissary veins:
- anterior condylar vein connects the internal vertebral venous plexus to the internal jugular vein
- lateral and posterior condylar veins connect the external vertebral venous system with the internal jugular vein
Radiographic features
The posterior condylar vein is the most readily seen of the condylar emissary veins on imaging. It connects the deep cervical vein and the horizontal portion of the vertebral artery venous plexus with the superior bulb of the internal jugular vein. Therefore, the posterior condylar vein and deep cervical vein dilate significantly in internal jugular vein thrombosis.
