目的 提高對顯微鏡下多血管炎(MPA)的影像學和臨床表現的認識。
方法 對確診的一例以多葉段肺實變為特征的MPA患者進行回顧性分析。
結果 患者以咳嗽、咳痰、咯血伴發熱1周, 心悸、氣短2 d入院。臨床出現鏡下血尿, 蛋白尿, 心律失常, 鞏膜炎, 耳廓皮膚紅腫, 貧血, 體重下降等多系統損害。血沉明顯增快(150 mm/1 h), 經多種抗菌素、抗病毒藥物等治療無效。在CT定位下經皮肺穿刺活檢提示韋格納肉芽腫, 核周型抗中性粒細胞胞質抗體陽性, 診斷為MPA。給予強的松聯合環磷酰胺治療, 臨床癥狀明顯緩解, 實驗室指標好轉。
結論 臨床中對雙肺多葉段實變, 伴無法解釋的臨床多系統損害, 經抗炎、抗病毒等治療無效時, 要考慮到MPA, 應及時行經肺活檢及抗中性粒細胞胞質抗體檢查以早期診斷, 給予糖皮質激素聯合環磷酰胺治療, 療效佳。
