  • Title: Retropharyngeal pseudomeningocele presenting as dysphagia after atlantooccipital dislocation.
    Author: Cognetti DM, Enochs WS, Willcox TO.
    Journal: Laryngoscope; 2006 Sep; 116(9):1697-9. PubMed ID: 16955007.
    Abstract:
    EDUCATIONAL OBJECTIVE: At the conclusion of this paper, the readers should be able to recognize a retropharyngeal pseudomeningocele as a potential complication of atlanto occipital dislocation. OBJECTIVES: To demonstrate how a retropharyngeal pseudomeningocele may present as dysphagia in a patient who is recovering from atlanto occipital dislocation as well as to discuss the treatment options in this situation. STUDY DESIGN: Case report and literature review. METHODS: Analysis of a case through medical record and literature review. RESULTS: A retropharyngeal pseudomeningocele is a very rare complication of atlanto occipital dislocation. It may develop weeks after the initial injury and can present with respiratory or swallowing difficulties. Decompression via a ventriculoperitoneal or lumboperitoneal shunt facilitates resolution of the cerebral spinal fluid collection. CONCLUSIONS: A retropharyngeal pseudomeningocele should be considered in all patients status post-atlanto occipital dislocation who are experiencing respiratory distress or dysphagia.
