Grand Round—University Hospital of Wales, Cardiff: Pyrexia of unknown origin

摘要

Pyrexia of unknown origin is a common problem in medical practice and encompasses a broad spectrum of diagnostic possibilities. The clinical phenomenon of pyrexia of unknown origin was defined in 1961 as an illness persisting for three weeks or longer, with episodes of fever greater than 38.3℃ and with no diagnosis reached after one week of hospital 'investigation. This case highlights the difficulty that can be encountered in establishing a diagnosis in a patient presenting with pyrexia of unknown origin.
