Chiari Malformation is ‘crowding’ of the junction between the brain and spinal cord and can lead to Valsalva-induced occipital headaches and/or signs/symptoms related to dysfunction of the brainstem, cerebellum, or spinal cord. It is characterized on neuroimaging (typically MRI) by descent of the cerebellar tonsils 5 or more millimeters below the base of the skull at foramen magnum. Chiari malformation is found incidentally on neuroimaging in 1-3% of pediatric patients. The objective of this CLASP tool is to aid primary care providers in establishing appropriate neurosurgery follow up and educate caregivers on this diagnosis.
