BACKGROUND: Duplex sonography of the temporal artery may be helpful in the diagnosis of @entity226 . @entity1 AND METHODS: The superficial temporal arteries of 36 @entity1 with @entity226 or suspected @entity3468 were examined using both duplex ultrasonography (US) and biopsy. The data of these @entity1 were divided into two groups. Group A consisted of 24 @entity1 (66.7%) with definite positive results using duplex (US) and Group B of 12 @entity1 (33.3%) who showed a suspicious or negative ultrasonographic result. RESULT: In all @entity1 of Group A, the histological findings corresponded with the ultrasonographic changes in the inflamed artery. - The characteristic ultrasonographic sign was a dark halo around the lumen of the temporal arteries. There was a high correlation between a bilateral halo found by US with an ocular involvement. Ten out of 14 @entity1 with a bilateral halo (71.4%) showed a distinct involvement of the optic nerve or retina. - The characteristic histological signs were infiltration of the vessel wall by inflammatory cells, mainly lymphocytes. Group B: The biopsies of the superficial temporal arteries were positive in 8 @entity1 (66.7 %), negative in 4 other @entity1 (33.3%). CONCLUSION: @entity1 with a distinct halo, demonstrated by US, also showed corresponding pronounced inflammatory cell infiltration of the vessel wall. @entity1 with no ultrasonographic changes presented histological signs of @entity32 such as isolated inflammatory cells around the vasa vasorum and/or in the adventitial layer.
