Last revised by Dr Daniel J Bell on 17 Dec 2019

The condylar emissary veins (anterior, lateral, posterior) are major posterior cranial fossa emissary veins:

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.
