We report a 17-year-old male patient with a presyrinx state due to Chiari malformation. Neurological examination revealed weakness of both upper extremities. MRI image revealed a Chiari malformation and hyperintensity on a T2 weighted image at the gray matter of cervical spine. The patient underwent enhanced MRI and angiography, but there were no abnormalities evident on these examinations. We underwent foramen magnum decompression, C1 laminectomy, and duroplasty for the Chiari malformation. The hyperintensity of the spinal cord evidenced on the T2-weighted image was improved a week later. We were able to prevent progression to syringomyelia by properly treatmening the presyrinx state.
