Introduction

In December 2019, novel corona virus (COVID-19), aka severe acute respiratory syndrome corona virus-2 (SARS-COV-2) infection has out break as an global pandemic with high number of reporting cases worldwide.

It is manifested by respiratory symptoms due to lung involvement.

The imaging features of COVID-19 pneumonia were well described as multifocal peripheral ground glass opacities with or without consolidation⁽¹⁾⁽²⁾.

However these are not specific and can be seen in other diseases like viral pneumonia, eosinophilic pneumonia or cryptogenic organizing pneumonia.

There has been some literature evidences regarding microvascular damage of pulmonary arteries, cytokine release syndrome (CRS) and hypercoagulability due to proinflammatory state which leads to thromboembolic events, multiorgan complications.
