A case-report of widespread pulmonary embolism in a middle-aged male seven weeks after asymptomatic suspected COVID 19 infection.

Background: Pulmonary embolism (PE) is seen in high frequency in hospital-treated patients with Covid-19. We present a case of suspected Covid-19 with long-term dyspnea and widespread PE.

Case Presentation: A 51- year old male, with no prior medical history, no medication, and non-smoker arrived at the emergency department with exercise induced dyspnea during 4-5 weeks and for the last 48 h dyspnea at rest. Seven weeks before hospitalization, he felt difficulties taking deep breaths for some days but no other symptoms. Oxygen saturation at rest was 93%. Troponin T was 1200 mg/L (ref < 15 mg/L). CT angiography revealed widespread bilateral segmental pulmonary embolism. Additional findings were ground glass opacities that could match Covid-19. The patient tested negative for SARS -CoV-2. Full dose tinzaparin was given for 2 days in hospital, followed by apixaban for 6 months. Recovery has been uneventful so far.

Conclusions: Long-term breathing difficulties might be relatively common after non-hospitalized symptomatic Covid-19. The frequency of PE in this group is unknown. We report a case of suspected covid-19 with widespread PE and a long history of dyspnea but no other symptoms. In our case slight hypoxia and laboratory testing indicated significant disease, which was proven with contrast angiography. This case shows that PE is a differential diagnosis in non-hospitalized symptomatic Covid-19 with persisting breathing problems.
