Condylar canal

The condylar canal (canalis condylaris) is located in the condylar fossa, posterior to the occipital condyles. It transmits the emissary veins which originate at the sigmoid sinus and drain into the occipital vein.

The condylar canaI has a variable presence and seen only in ~55% (range 50-60%) of cases. It is more commonly bilateral.

Identification of this structure and its role as an alternative source of venous drainage from the brain will help avoid misinterpretation.
