Petroclinoid ligaments

Last revised by Dr Yuranga Weerakkody on 21 Mar 2014

The petroclinoid ligaments are a fold of the dura mater that extends between the anterior and posterior clinoid processes and the petrosal part of the temporal bone.

Thus there are two separate bands, which are termed the “anterior” and “posterior” petroclinoid ligaments respectively. The anterior petroclinoid ligament is considered to be an extension of the tentorium cerebelli, while the posterior petroclinoid ligament arises from posteromedial extensions of the tentorial notch. 

The petroclinoid ligament may calcify as other structures that you can see in normal intracranial calcifications.
