Granulomatosis with Polyangiitis Presented with Temporal Headache and Tenderness

Abstract

Granulomatosis with polyangiitis is a necrotizing vasculitis affecting small blood vessels, primarily in the upper and lower respiratory tracts and kidneys. When limited to the upper respiratory tract or nervous system without kidney involvement, it's termed limited granulomatosis with polyangiitis. Diagnosing this variant can be challenging, particularly with negative antibody tests. We report a case of a patient experiencing temporal headaches and tenderness, raising suspicion for temporal arteritis or limited granulomatosis with polyangiitis.
