Interstitial lung diseases (ILD) can occur due to various known or unknown causes. They usually present with dry cough and exertional dyspnea. On radiology usual findings are ground glass opacities (GGO's), reticular shadows, nodules etc. Some patients after acute COVID-19 (coronavirus disease 2019) suffer from persistent symptoms/manifestations. These have been called 'Long COVID'. Long COVID also has radiological features like GGO's, nodules and reticulations. Further, patients even without history of acute COVID-19, can also present with 'Long COVID'. In the present case series, we describe three such cases with no history of having suffered from COVID-19, presenting with ILD like features and diagnosed as Long COVID. We infer from these cases that 'Long COVID' can both clinically and radiologically mimic ILD's. Hence, emphasizing the fact that in the present COVID-19 pandemic situation, 'Long COVID should be a differential diagnosis to be considered while making a new diagnosis of ILD.
间质性肺疾病（ILD）可由各种已知或未知原因引起。它们通常表现为干咳和劳力性呼吸困难。在放射学上，常见表现为磨玻璃影（GGO）、网状阴影、结节等。一些急性新型冠状病毒肺炎（COVID-19，冠状病毒病2019）患者会出现持续症状/表现。这些被称为“长新冠”。“长新冠”也有放射学特征，如磨玻璃影、结节和网状影。此外，即使没有急性COVID-19病史的患者也可能出现“长新冠”。在本病例系列中，我们描述了3例无COVID-19病史、表现出ILD样特征并被诊断为“长新冠”的病例。我们从这些病例中推断，“长新冠”在临床和放射学上都可能酷似ILD。因此，强调在当前COVID-19大流行情况下，“长新冠 ”应作为新诊断ILD时需考虑的鉴别诊断。
