Clinical presentation can be confusing, silent, or overshadowed, so diagnosis is frequently delayed. Early diagnosis is mandatory and different imaging techniques play a pivotal role to screen the heart. Biological agents, including tumour necrosis factor inhibitors, show promising results. Cardiac surgery must be accompanied by immunosuppressive therapy to prevent iatrogenic or trauma-triggered pseudo aneurysm secondary to arterial hypersensitivity.
