The purpose of this article is to review the use of lung ultrasonography (US) in the workup of COVID-19 pneumonia. The scanning protocol, normal US appearance of lung, major US features of COVID-19 pneumonia, diagnostic performance of lung US and potential pitfalls when explaining US results are descripted and discussed. Lung US is increasingly accepted as a useful tool in the workup of COVID-19 pneumonia. Certain US imaging features allow to confirm or rule out the diagnosis for clinical management; on other hand, most US findings are nonspecific with technical limitations. Thus, it is important to recognize these drawbacks since the ignorance of potential pitfalls of lung US may lead to over diagnosis or missed diagnosis.

Key words: Lung ultrasonography; COVID-19 pneumonia; Technical limitation; Pitfalls
