A rare multi-system disease with an incidence of about 5/million per year, polyarteritis nodosa (PAN) occasionally may cause splenic vasculitis, usually at arteriole bifurcations, leading to multiple systemic infarcts with extensive confluent systemic necrosis. PAN may also be a cause of fleeting patchy pulmonary infiltrates or pulmonary nodular lesions. The diagnosis is usually difficult and delayed because the clinical manifestations are varied and depend on the site and the extent of the arterial involvement.
结节性多动脉炎（PAN）是一种罕见的多系统疾病，年发病率约为百万分之五，偶尔可引起脾血管炎，通常发生在小动脉分支处，导致多发性全身梗死并伴有广泛的融合性全身坏死。PAN也可能是短暂性斑片状肺浸润或肺结节性病变的病因。由于临床表现多样且取决于动脉受累的部位和范围，诊断通常很困难且会延迟。
