Post-COVID recurrent dyspnoea: A case report

Abstract

Rationale: Post-COVID symptoms need aggressive evaluation. Patient’s Concern: A 29-year-old male patient who had suffered from COVID-19 eight weeks earlier, presented with an acute onset of breathlessness and right-sided chest pain due to pneumothorax. Emergency tube thoracostomy was performed. However, it failed to improve hypoxia. Diagnosis: High-resolution computed tomography of the thorax with computed tomography pulmonary angiography revealed pulmonary arterial thrombosis, ground-glass opacities, and bilateral pneumatoceles. Interventions: Hospital admission and treatment with low molecular weight heparin at a dose of 1.5 mg/kg every 24 h. Outcomes: The large pneumatocele showed significant resolution after three months of follow-ups. Lessons: Being increasingly reported after having a SARS-CoV-2 infection, pneumatocele formation, due to post-COVID lung scarring and late vascular thrombotic events, is a peculiar sequela and can present as acute dyspnoea. Long-term preventive anticoagulants after recovery from COVID-19 are necessary. Breathing exercises during recovery should be done with caution.
