Craniocervical Pneumatization

open access: yesJournal of Radiology Case Reports, 2013
Craniocervical bony pneumatization is a rare finding, with limited numbers of cases reported in the literature. It is thought to be linked to Eustachian tube dysfunction and a ball valve mechanism, and has a link with recurrent Valsalva maneuvers. We report a case of pneumatization of the occiput, atlas (C1) and axis (C2) in a patient with extensive ...
