A patient with suspected giant cell arteritis and prior negative findings on superficial temporal artery biopsy was evaluated with 320-detector row CT angiography (CTA) and whole-brain perfusion. Corticosteroid treatment was initiated on the basis of CT angiography findings of arteritis and a cortical perfusion deficit. The patient's symptoms and perfusion imaging findings resolved following therapy. Whole-brain CTA and imaging was helpful in the diagnosis and monitoring this patient with suspected vasculitis.
一名疑似巨细胞动脉炎且颞浅动脉活检先前结果为阴性的患者接受了320排CT血管造影（CTA）和全脑灌注评估。基于动脉炎的CT血管造影结果和皮质灌注缺损开始使用皮质类固醇治疗。治疗后患者的症状和灌注成像结果得到缓解。全脑CTA和成像有助于诊断和监测这名疑似血管炎的患者。
