Arcuate foramen
In human anatomy, arcuate foramen, also known as ponticulus posticus (Latin for "little posterior bridge"), refers to a bony bridge on the atlas (C1 vertebra) that covers the groove for the vertebral artery. It is a common anatomical variation and estimated to occur in approximately 3-15% of the population.[1][2][3] It occurs in females more commonly than males.[2][4] The ponticulus posticus is created through ossification of the posterior atlantooccipital ligament.
Pathology
The presence of arcuate foramen is associated with headache, musculoskeletal pain[2] and vertebrobasilar stroke.[1]
