A case report of pyrexia of unknown origin in a 15-year-old boy

Abstract

We present a case of a 15-year-old boy presenting with a 3-week history of fever whilst visiting relatives in the United Sates (US). Despite extensive workup, a definitive diagnosis was not reached. The clinical history and course of the disease required consideration of broad range of differential diagnosis. This case highlights the importance of clinical history and examination in the assessment of fever of unknown origin (FUO).
