Extraordinary Complication of COVID-19 Swab Testing: CSF Rhinorrhea.

Coronavirus disease 2019 (COVID-19) is a highly contagious disease that has reached pandemic status. The diagnosis of COVID-19 is made using the polymerase chain reaction test to evaluate a swab taken from the naso/oro-pharyngeal area. Since COVID-19 is still a pandemic, it is thought that the use of this diagnostic test will be on the agenda for a while. A patient with COVID-19 symptoms presented with unilateral cerebrospinal fluid rhinorrhea after a nasopharyngeal swab test. Although nasopharyngeal swabs are taken very frequently, the complication rate is very low. However, life-threatening complications can be observed on rare occasions, and care should be taken.
