Background:
Due to the SARS-CoV-2 virus pandemic and its rapid spread worldwide, an early and effective detection strategy was the nasopharyngeal reverse transcription polymerase swab tests, a procedure still performed today. A relatively safe procedure when done correctly, however, one of the rare complications reported in the literature includes a cerebrospinal fluid (CSF) leak.
Case Description:
A 69-year-old female patient presented to the emergency department with clear fluid rhinorrhea, clinically diagnosed with a CSF fistula after a SARS-CoV-2 nasopharyngeal swab. Resulting computed tomography and magnetic resonance images did not report any abnormalities; however, persistence of clear fluid rhinorrhea obligated pharmacological treatment without resolution, requiring insertion of a lumbar catheter to achieve clinical resolution.
Conclusion:
It is essential to train staff to correctly administer nasopharyngeal swabs and thus reduce the rate of complications, as well as early recognition of symptoms and signs of CSF fistula.
