Radiological evolution of peri-odontoid pannus in a patient with Chiari I malformation: a case-based review

Abstract

This case illustrates the resolution of a significant and symptomatic peri-odontoid pannus in a patient with CIM without craniocervical fusion or odontoidectomy. Such a case indicates that not all peri-odontoid pannus formations in CIM patients are due to hypermobility at the craniocervical junction.
