Pulmonary Embolism: novel corona virus versus tuberculosis

This series describes six paediatric cases who presented as severe acute respiratory illness during the pandemic of covid-19 with high D-dimer levels. All six patients tested negative for novel corona virus. They were diagnosed as having tuberculosis on detailed investigations; High D-dimer levels are one of the most important indicators of the pulmonary embolism. Pulmonary embolism is a rare presentation of tuberculosis and this study emphasizes the need of keeping tuberculosis as an important differential diagnosis of those who present as acute respiratory distress syndrome.
