Evaluation of taste and smell disorders in pediatric COVID-19 Cases

Abstract

Objective: Pediatric coronavirus disease 2019 (COVID-19) cases have a high risk of contagiousness, as they usually progress with asymptomatic or mild respiratory symptoms. Disorder in taste and/or smell has rarely been reported in pediatric cases. In our study, early diagnosis and isolation measures were emphasized by evaluating the clinical, laboratory, and radiological imaging findings of pediatric COVID-19 cases presenting with symptoms of taste and/or smell disorder.

Methods: Seven cases aged 0-18 years were included in the study. The severe acute respiratory syndrome coronavirus-2 polymerase chain reaction test was performed for the seven cases presented with taste and/or smell disorders. Clinical findings, laboratory tests, and radiological imaging of all the cases were evaluated on the day of admission and on the fifth day.

Results: Seven (5.7%) of 122 pediatric COVID-19 cases had disorder in taste and/or smell. In two cases, pneumonia findings were detected in thorax computed tomography imaging. It was observed that all the patients fully recovered at the latest on the 21st day. In the cranial diffusion magnetic resonance imaging of a case, diffusion restriction was detected in the corpus callosum splenium.

Conclusion: Although less common than adults, children with COVID-19 may also have taste and smell disorders, and this may be accompanied by central nervous system imaging findings.
