Aortic dissection presenting as fever of unknown origin

Aortic dissection most often presents with the severe chest pain and may have variable symptoms including fever. However, fever of unknown origin as the predominant manifestation of aortic dissection seems to be extremely rare. We report the case of a patient who sustained a prolonged spiking fever with unknown origin for 17 days following acute aortic dissection. The case serves as a reminder that prolonged fever may be the principal residual sequelae after aortic dissection.
