To describe the relationship between coronavirus disease 2019 (COVID-19) and pulmonary tuberculosis during the current pandemic, as well as to describe the main computed tomography (CT) findings in patients suffering from both diseases simultaneously.
This was a retrospective, cross-sectional observational study of the chest CT scans of 360 patients with COVID-19, as confirmed by RT-PCR.
In four (1.1%) of the patients, changes suggestive of COVID-19 and tuberculosis were observed on the initial CT scan of the chest. On chest CT scans performed for the follow-up of COVID-19, cavitary lesions with bronchogenic spread were observed in two of the four patients, whereas alterations consistent with the progression of fibrous scarring related to previous tuberculosis were observed in the two other patients. The diagnosis of tuberculosis was confirmed by the isolation of .
Albeit rare, concomitant COVID-19 and tuberculosis can be suggested on the basis of the CT aspects. Radiologists should be aware of this possibility, because initial studies indicate that mortality rates are higher in patients suffering from both diseases simultaneously.
描述2019冠状病毒病（COVID-19）与当前大流行期间肺结核之间的关系，并描述同时患有这两种疾病的患者的主要计算机断层扫描（CT）表现。
这是一项对360例经逆转录聚合酶链反应（RT-PCR）确诊的COVID-19患者胸部CT扫描的回顾性横断面观察研究。
在4例（1.1%）患者的胸部初次CT扫描中观察到提示COVID-19和肺结核的改变。在对COVID-19进行随访的胸部CT扫描中，4例患者中有2例观察到有空洞形成并伴有支气管播散的病变，而另外2例患者观察到与既往肺结核相关的纤维瘢痕进展一致的改变。通过分离……确诊为肺结核。
尽管罕见，但根据CT表现可提示COVID-19与肺结核并存。放射科医生应意识到这种可能性，因为初步研究表明，同时患有这两种疾病的患者死亡率更高。
