Abstract:
We report a case of a 52-year-old female with Large Vessel Vasculitis (LVV) after vaccination with Oxford-AstraZeneca COVID-19 vaccine. She was presented with fever, started two weeks after the second dose of vaccine. Laboratory values, revealed elevated inflammatory markers and chronic disease anaemia. All the infectious causes were excluded, and immunology tests were negative. Computed Tomography (CT) demonstrated concentric wall thickening of ascending and descending aorta. Positron Emission Tomography (PET) scan showed increased vascular fluorodeoxyglucose (FDG), compatible with LVV. Within one month of treatment with high dose glucocorticoids and iv cyclophosphamide, laboratory findings normalised, and fever resolved.
