Spreading swiftly across the borders and over the seas, severe acute respiratory syndrome-related coronavirus-2 (SARS-COV-2), as causative pathogen of coronavirus disease 2019 (COVID-19), is currently the main global public health concern. "Cannonball appearance," as a rare and yet underrated CT feature of COVID-19 pneumonia, has been typically linked to certain hematogenous pulmonary metastases and some inflammatory/infection conditions, including tuberculosis, but no other viral or atypical pneumonia. Cannonball appearance can bring diagnostic dilemmas and difficulties in monitoring treatment response in patients with or suspicious for hematogenous pulmonary metastasis. Hereby, we report two cases of COVID-19 delta variant-induced pneumonia manifesting unusually in chest CT scan with cannonball appearance.
迅速蔓延至境外和海外的严重急性呼吸综合征相关冠状病毒 2（SARS-COV-2），是导致 2019 年冠状病毒病（COVID-19）的病原体，目前是全球主要的公共卫生关注点。“炮弹征”，作为 COVID-19 肺炎的一种罕见且尚未得到充分重视的 CT 特征，通常与某些血行性肺转移和一些炎症/感染性疾病有关，包括结核，但与其他病毒性或非典型性肺炎无关。“炮弹征”可导致血行性肺转移患者或疑似血行性肺转移患者的诊断困境和治疗反应监测困难。因此，我们报告了两例 COVID-19 德尔塔变异株引起的肺炎，其在胸部 CT 扫描上表现出异常的“炮弹征”。
