Abstract:
Kimmerle’s anomaly is a rare and serious pathology of the 1st cervical vertebra, which may
sometimes lead to hardly explicable changes in vertebrobasilar circulation. Also known as
ponticulus posticus (PP), this phenomenon encircles the vertebral artery and suboccipital
nerve and is associated with vertigo, vertebro-basilar insufficiency, neck pain, shoulder pain
and cervicogenic headache symptoms. It can also lead to migraine as a result of its
interaction with dura. As the knowledge of this variant by clinicians is important for
obtaining a fast result in the treatment, it should also be taken into account in surgical
approaches so as not to harm the vessels and nerves in this area.
