Today, we reviewed an excellent case of GCA presenting as acute left sided chest pain with asymmetric BP readings and imaging evidence of aortitis.
- There are two large vessel vasculitides that can involve the aorta and its major branches including: Takayasu arteritis and giant cell arteritis.
- The two disorders are indistinguishable histopathologically (both show granulomatous inflammation). Distinction between the two is based on age (>50 years for GCA, < 40 years for Takayasu) and distribution of lesions (primarily external carotid artery branches for GCA and aorta and branches for Takayasu).
- Treatment for both involves high dose steroids with very gradual taper.
