A 73-year-old end-stage renal disease patient who had undergone craniopharyngioma resection 30 years previously was admitted to hospital after a fall. He developed hospital-acquired laboratory-confirmed SARS-CoV-2 that required high-flow nasal oxygen therapy. Follow-up real-time polymerase chain reaction (RT-PCR) of nasopharyngeal swabs was performed weekly by a trained nurse until hospital discharge 3 weeks later.

The following month, the patient developed tiredness, discomfort in the back of his throat, swallowing difficulties, weight loss (> 10kgs) and fever (39 °C).
