There are sparse published data on the natural history of "benign" Chiari I malformation (CM-I)-i.e., Chiari with minimal or no symptoms at presentation and no imaging evidence of syrinx, hydrocephalus, or spinal cord signal abnormality. The purpose of this study was to review a large cohort of children with benign CM-I and to determine whether these children become symptomatic and require surgical treatment.

Patients with “benign” Chiari I malformations require surgical decompression at a low rate
