Temporal arteritis presenting with facial swelling and a negative temporal artery biopsy.

ABSTRACT

A man in his 60s presented to the emergency department with marked bilateral preauricular swelling, associated with jaw claudication, temporal tenderness and blurred vision. He was immediately treated for temporal arteritis by commencing systemic corticosteroids. A temporal artery biopsy showed no evidence of vasculitis. However, positron emission tomography-CT demonstrated increased uptake in the medium-large vessels, including the left superficial temporal artery and aorta. This case illustrates that facial swelling may be an under-recognised presenting feature of temporal arteritis, and that a negative temporal artery biopsy does not always rule out a diagnosis of temporal arteritis, and should not delay treatment.
