Temporal Arteritis definition
What TEMPORAL ARTERITIS means: Temporal Arteritis - also called giant cell arteritis (GCA) is an inflammatory disease of blood vessels (most commonly large and medium arteries of the head). It is therefore a form of vasculitis. The name comes from the most frequently involved vessel (temporal artery which branches from the external carotid artery of the neck). The alternative name (giant cell arteritis) reflects the type of inflammatory cell that is involved (as seen on biopsy).
