Multiplanar CT and MRI of collections in the retropharyngeal space: is it an abscess?
OBJECTIVE: The purpose of this article is to describe a practical imaging approach to evaluating collections in the retropharyngeal space. CONCLUSION: The differential diagnoses for fluid in the retropharyngeal space include both noninfectious and infectious processes. The multiplanar capabilities of CT and MRI are ideal for characterizing and delineating collections. In this pictorial essay, we describe the anatomy of the retropharyngeal space and offer a four-step approach to evaluating retropharyngeal collections on multiplanar imaging.
