Abstract

A patient with Klippel-Feil syndrome reported with a pneumatocyst of the proximal epiphysis of a right cervical rib. There was no additional skeletal abnormality except for fusion of the C3 and C4 vertebral bodies. To the best of our knowledge, this is the first reported instance of this particular association.


Key Points


* Pneumatization in bones is a very rare entity that commonly results from habitual valsalva maneuvers and some pathological processes including osteomyelitis, osteonecrosis, neoplasm, or trauma.


* Klippel-Feil syndrome is a clinical and radiologic entity with numerous associated anomalies and a variety of complications including cervical ribs.


* Pneumatization of a cervical rib, as far as we know, was not reported before solely or in association with Klippel-Feil syndrome; therefore, our case may have coincidental findings and the confirmation of any association requires new additional cases.
