Reason: suboptimal MRI CSF flow study on 1/3/2015. Radiologist recommended to repeat flow sequence with no additional change to the patient. History: Chiari malformation. There are mildly low-lying cerebellar tonsils. There is intact CSF flow across the anterior foramen magnum, but blunted CSF flow posteriorly at the level of the cerebellar tonsils.
