Abstract：
Description Lung cavitation as a complication of COVID-19 is rare. A 56-year-old male presented with lung cavitation, small volume hemoptysis, and violaceous discoloration of the right great toe, 5 weeks after diagnosis with COVID-19 pneumonia. The digital changes were consistent with previously described microvascular changes called \"COVID toe.\" CT angiography of the chest was negative for pulmonary embolism but showed a 2.5 x 3.1 x 2.2 cm cavitation within the right lung. Extensive evaluation for commonly implicated infectious and autoimmune causes was negative. We concluded that the cavitary lung lesions were likely a complication of COVID-19 pneumonia and may implicate microangiopathy as an important component of pathogenesis. This case highlights a rare complication of COVID-19 of which clinicians should be aware.
摘要：
描述肺空洞作为COVID-19的并发症很少见。一名56岁男性出现肺空洞,小体积咯血,和右大脚趾的暴力变色，诊断为COVID-19肺炎后5周。数字变化与先前描述的称为“COVID脚趾”的微血管变化一致。胸部CT血管造影显示肺栓塞阴性，但右肺有2.5x3.1x2.2cm空化。对常见感染和自身免疫原因的广泛评估为阴性。我们得出的结论是，空洞性肺病变可能是COVID-19肺炎的并发症，并可能暗示微血管病是发病机理的重要组成部分。该病例突出了COVID-19的罕见并发症，临床医生应该注意。
