What are Craniovertebral junction anomalies?

What are Craniovertebral junction anomalies?

Craniocervical junction abnormalities are congenital or acquired abnormalities of the occipital bone, foramen magnum, or first two cervical vertebrae that decrease the space for the lower brain stem and cervical cord.

What is Craniovertebral Junction?

The craniovertebral junction (CVJ) comprises the occiput, atlas, and axis and is visible in most magnetic resonance (MR) imaging studies of the brain. Except for fusion anomalies, abnormalities of the axis are primarily confined to the odontoid process and are not associated with basilar invagination.

What is Cvj anomaly?

Craniovertebral junction (CVJ) anomalies can be congenital, developmental or due to malformation secondary to any acquired disease process. These anomalies can lead to cranial nerve compression, vertebral artery compression, and obstructive hydrocephalus.

What is OS Odontoideum?

Os odontoideum is a rare condition of the cervical spine. It occurs when a separation occurs at the top of the spine. The tip of the second cervical vertebra is called the odontoid. In os odontoideum, the tip of the odontoid becomes separated from the remainder of the vertebra, which can lead to spinal instability.

What is Cvj in pregnancy?

The craniovertebral junction (CVJ) is composed of the occiput, the. foramen magnum. , and the first two. cervical vertebrae.

What is Cvj in ultrasound?

The craniovertebral junction (CVJ) comprises the occiput, atlas, and axis and is visible in most magnetic resonance (MR) imaging studies of the brain. Occiput anomalies include condylus tertius, condylar hypoplasia, basiocciput hypoplasia, and atlanto-occipital assimilation.

Can neck problems cause pressure in head?

The nerves and muscles in the neck can cause pain in the head. Sometimes pressure or pain appears in both the head and the neck. This can be caused by headaches, such as tension headaches or migraines. Other causes include whiplash, muscle strain, and concussions.
