A 35-year-old woman presented with anosmia after recovery from COVID-19. About two weeks before the anosmia, she had experienced low-grade fever, dry coughing, and headache. Due to the outbreak of COVID-19, physicians evaluated her for SARS-CoV-2 paraclinical examinations. Her lab test revealed positive CRP (3+) and lymphopenia. Chest CT scan showed patchy ground-glass and peripheral infiltration (Figure 1). A throat swab sample was taken, and reverse real-time PCR assay confirmed SARS-CoV-2 infection.
She was referred to an otolaryngologist for her anosmia. A complete head and neck examination was performed. The nasal cavity, oral cavity, and cranial nerve functions (II-V, VII-IX, and XII) were normal. The patient was diagnosed with postviral olfactory dysfunction. Rhinocort spray, one puff BID for 10 days, was prescribed for her. However, no improvement was observed. A throat swab sample was taken, and reverse real-time PCR was performed again. The second PCR result was negative. Oral prednisolone was prescribed. After 6 days of consuming prednisolone, her anosmia reversed.
