Atypical Presentation Of Granulomatosis With Polyangiitis – A Challenge In Diagnosis Of FUO

Abstract

Fever of unknown origin (FUO) is far more often caused by an atypical presentation of a rather common disease than by a very rare disease. Most common causes of FUO are infectious, inflammatory and neoplastic. Hereby, we present a case of FUO with granulomatosis with polyangiitis as its etiology with an atypical presentation.
