In most instances, the laminectomy is limited to C1, the first cervical vertebra. It sits above the opening of the skull, called the foramen magnum. An MRI uses a magnetic field and radio waves to produce cross-sectional images of particular organs and bodily tissues. Winn RH, ed.

Imaging differential considerations include: Chiari 1.5 malformation (sometimes considered a variant of Chiari I malformation 4), idiopathic intracranial hypertension (pseudotumor cerebri). Many cases with this anomaly leave a portion of the spinal cord exposed through the spinal canal, typically forming a sac filled with cerebrospinal fluid, meninges, and portions of the spinal cord and nerves (myelomeningocele). Affected individuals may have some of the symptoms described above. Vertigo, dizziness, ringing in the ears (tinnitus) and bilateral hearing impairment can also develop. When the tonsils protrude through the foramen magnum, they block the proper flow of cerebrospinal fluid between the skull and the spinal cord, potentially compressing the brainstem (pons medulla) and the upper portion of the spinal cord. The likelihood of becoming symptomatic is proportional to the degree of descent of the tonsils. In: Atlas of Normal Imaging Variations of the Brain, Skull, and Craniocervical Vasculature.
