From: D-dimer as a biomarker for disease severity and mortality in COVID-19 patients: a case control study

A 59-year-old male diagnosed with COVID-19 who presented with fever, coughing, and hemoptysis. Chest CT upon admission showing ground glass opacities and patchy consolidation (a). He had an elevated D-dimer level of 9.43 mg/L. Wells’ score, Geneva score, and CURB65 score were 7, 7, and 2 respectively. Wells’ score suggested high probability of pulmonary embolism. CT pulmonary angiography (b, c) and Doppler ultrasonography (d) were then carried out and ruled out pulmonary embolism and deep vein thrombosis in the lower extremities
