Giant Cell Arteritis (GCA)

Giant cell arteritis, also known as temporal arteritis, is the inflammation of certain arteries that occurs in adults who are usually over the age of 50. The temporal artery that runs along the side of the head in the temple area is commonly affected. The condition can cause headaches, facial pain, joint pain, fever, and problems with vision. The exact cause of the condition is unclear. The condition may be difficult to identify because of the wide range of symptoms. Diagnosis may be made by studying a biopsy of the temporal artery and performing a blood test. The condition can usually be treated using corticosteroid medication.
