CTA or MRA for evidence of large vessel involvement
PET for evidence of aortic inflammation
ESR is <50 in 10 % and< 40 in 5.8 %, CRP more sensitive
Other labs- anemia, increased Platelets,fibrinogen and alk phos occur
some use aspirin
65 % have visual obscurations before permanent visual loss, on average 8.5 days before
Contralateral eye may be affected, average, 5 days after first eye has visual loss.
lack of relief with prednisone is a sign of wrong diagnosis
1990 criteria require 3/5:
new onset headache or new type of headache
age > 50
TA tender orpulseless, unrelated to atherosclerosis
WSR> 50
Abnormal biopsy with inflammation and multinucleate giant cells
