Malformations of the craniocervical junction: Casamassima-morton-nance syndrome and type I Chiari malformation

Abstract

Introduction: Casamassima-Morton-Nance syndrome (CMNS) is a rare pathology with few reports in the literature. CMNS, Jarcho-Levine syndrome and the Lavy-Moseley syndrome must be considered among the differential diagnoses on those patients with vertebral and costal arch segmentation deficiencies. Objectives: We report a case of a 13-year-old girl without a history of consanguinity presenting to the spine clinic with cervicalgia and was found to have altered segmentation of her spine and costal arcs as well as a Chiari type I malformation. Conclusion: CMNS is a rare condition with few reported cases in the literature. Due to the associated conditions patients have a short life span. In this report, we present the case of a 13-year-old girl with CMNS, CC junction abnormalities, and Chiari type I malformation.
