Giant cell arteritis presenting as facial swelling.

Facial swelling is commonly ascribed to angioedema and a host of other causes. Temporal arteritis (TA), a disease most often diagnosed in patients over the age of 50 years, frequently presents with nonspecific and often ignored complaints (headache, symptoms of polymyalgia rheumatica, low-grade fever, fever of unknown origin, loss of appetite, depression, joint pains, weight loss, hair loss, and even respiratory symptoms). The diagnosis of TA is highly likely in the presence of new-onset headaches, polymyalgia rheumatica, and a tender, cord-like, or swollen temporal artery. Facial swelling must be appreciated as another presentation of TA, especially when accompanied by other nonspecific symptoms. High clinical suspicion, immediate treatment, and definitive diagnosis by temporal artery biopsy are necessary to prevent the most severe vascular complications of blindness and cerebrovascular accidents. Treatment with corticosteroids is most often successful. Because this treatment is fraught with all the risks of high-dose and prolonged steroid therapy, it should only be initiated in cases of significant clinical suspicion, followed by a timely temporal artery biopsy to confirm the diagnosis. Delay in therapy increases the risk of a vascular catastrophe. Delay in obtaining a temporal artery biopsy after therapy has been initiated decreases the diagnostic sensitivity of the test. Other modalities of immunosuppressive therapy remain either unsuccessful or unproven. Concomitant low-dose aspirin therapy appears to hold promise.
