Giant cell arteritis associated with pericarditis and large vessel disease.

Giant cell arteritis is well recognised to affect branches of the external carotid artery and to cause systemic symptoms, but may also involve branches of the aorta producing a clinical syndrome that may be difficult to diagnose. A patient is described who presented with limb ischaemia, pericarditis and systemic symptoms. Treatment with corticosteroids improved the systemic manifestations but not the ischaemia. The patient died of bowel infarction four months after treatment was commenced.
