Observation of Retropharyngeal Fluid Collection in 2 COVID-19 Positive Patients

Abstract

Our understanding of the novel coronavirus, COVID-19, is growing; yet, there remains much we do not understand, and unique presentations are abundant. One potential presentation is retropharyngeal edema, defined as fluid in the retropharyngeal space. Multiplanar imaging with computed tomography or magnetic resonance imaging is ideal for characterizing and diagnosing these fluid collections rapidly as possible life-threatening complications may develop (eg, airway obstruction and mediastinitis). Here, we discuss the presentation, imaging identification, treatment, and recovery of retropharyngeal fluid collection in 2 COVID-19 cases. The significance of this article is to suggest conservative management as a viable treatment option for retropharyngeal fluid collection, as opposed to incision and drainage, in the setting of COVID-19.
