%X Chiari malformations (CM) are a spectrum of hindbrain abnormalities involving the cerebellum, brainstem, skull base, and cervical cord. The most common is Chiari I malformation, in which the cerebellar tonsils descend through the foramen magnum. As opposed to types II-IV, which are congenital, type I can manifest in late childhood or adulthood with headaches and focal neurological symptoms. It can be caused by genetic variation, conditions that alter the basal skull or increase intracranial pressure, and even injury. Syringohydromyelia (SHM) is a neurological disorder characterized by longitudinal dilation of the central canal of the spinal cord with accumulated cerebrospinal fluid. This case report demonstrates a 35-year-old male with headaches, neck pain, back pain, and paresthesias who was found to have CM type-I malformation and syringohydromyelia.
