Along with older age and consolidation pattern,enlarged mediastinal lymphadenopathy was found to be an independent predictor of 30-day mortality in patients with COVID-19.

Although enlarged mediastinal lymphadenopathy was reported as an atypical radiological finding, mediastinum should be evaluated for the presence of enlarged mediastinal lymphadenopathy and it may be useful as a biomarker for progressive disease.

In our study, we aimed to assess the prognostic role of enlarged mediastinal lymphadenopathy in a large group of patients with COVID-19.

In addition, we summarized the number and the distribution of enlarged mediastinal lymphadenopathy in patients with COVID-19.

Our data showed that older age, the presence of consolidation and enlarged mediastinal lymphadenopathy on CT scan were independently associated with increased 30-day mortality.

The distribution and the median number of enlarged mediastinal lymphadenopathies did not differ between dead and alive patients, however patients who died tended to have more lymph nodes than those who survived.
