Abstract
COVID-19 shares some features of giant-cell arteritis, in which the diagnosis
needs a high suspicion for prompt investigation and therapy. When the diseases
coexist this might lead to diagnosis delay with grave consequences. We reported
a case of a post-COVID-19 giant cell arteritis and polymyalgia rheumatica with
visual loss. We treated the patient with pulse methylprednisolone 1 gm daily for
3 consecutive days followed by 60 mg prednisolone for 4 weeks until
normalization of ESR, and then, gradual withdrawal. Oral Paracetamol,
vitamin-D3, and calcium carbonate were added to the treatment regimen. The
headache continued, so, we started perineural injection therapy (PIT) once
daily, for 6 sessions, at which the headache was completely resolved after the
third injection. The vision was regained completely after the sixth
injection.
