Differential diagnosis of parapharyngeal abscess with multisystem inflammatory syndrome in children associated with COVID-19

Abstract

The pandemic of the new coronavirus infection (COVID-19) has identified new diagnostic and medical tasks before different doctors. As observations show, children have the flow of infection easier than adults. However, in some cases, COVID-19 in children proceeds extremely difficult, with fever and multisystem inflammation, possibly requiring treatment in the resuscitation department. In domestic practice, the term "Multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19" is used to indicate the disease. Among the local symptoms of MIS are inflammations of the skin and mucous membranes, as well as various lymphadenopathy. The article presents the results of our clinic's observation of 205 patients with MIS for the period from May 2020 to May 2021. In some patients, the clinical manifestations of MIS-C required differential diagnosis with parapharyngeal abscesses (PPA). For this purpose, the children were consulted by an otorhinolaryngologist and a CT scan of the neck with contrast enhancement was performed. Despite the striking clinical manifestations similar to PPA, in no case was a pharyngeal abscess revealed. Both of these diseases are potentially fatal if treatment is not started on time, and therefore we believe that the awareness of otorhinolaryngologists about the manifestations of MIS-C will be useful in modern clinical practice.
