We investigated the diagnostic value of inflammation limited to the adventitia (ILA), and isolated vasa vasorum or small-vessel vasculitis (VVV, SVV) in temporal artery biopsies (TAB) for giant cell arteritis (GCA).
Two pathologists reviewed consecutive first TAB. Using the clinical diagnoses as the gold standard, positive predictive values (PPV) were calculated.
Among the 75 patients without classic TAB features of GCA, 8 had GCA diagnoses. The PPV of ILA, VVV, and SVV seen by either or both pathologists were 17%, 0%, and 7%, and 17%, 0%, and 10%, respectively.
(Peri)adventitial infiltrates in TAB poorly predict GCA.
我们研究了颞动脉活检（TAB）中仅局限于外膜的炎症（ILA）、孤立的滋养血管或小血管血管炎（VVV、SVV）对巨细胞动脉炎（GCA）的诊断价值。
两名病理学家回顾了连续的首次TAB。以临床诊断作为金标准，计算阳性预测值（PPV）。
在75例无GCA典型TAB特征的患者中，8例被诊断为GCA。两名病理学家中任何一人或两人观察到的ILA、VVV和SVV的PPV分别为17%、0%和7%，以及17%、0%和10%。
TAB中的（外膜周围）外膜浸润对GCA的预测性较差。
