Spontaneous tension pneumothorax and acute pulmonary emboli in a patient with COVID-19 infection.

The COVID-19 pandemic has had a significant impact on the structure and operation of healthcare services worldwide. We highlight a case of a 64-year-old man who presented to the emergency department with acute dyspnoea on a background of a 2-week history of fever, dry cough and shortness of breath. On initial assessment the patient was hypoxic (arterial oxygen saturation (SaO2) of 86% on room air), requiring 10 L/min of oxygen to maintain 98% SaO2 Examination demonstrated left-sided tracheal deviation and absent breath sounds in the right lung field on auscultation. A chest radiograph revealed a large right-sided tension pneumothorax which was treated with needle thoracocentesis and a definitive chest drain. A CT pulmonary angiogram demonstrated segmental left lower lobe acute pulmonary emboli, significant generalised COVID-19 parenchymal features, surgical emphysema and an iatrogenic pneumatocoele. This case emphasises the importance of considering coexisting alternative diagnoses in patients who present with suspected COVID-19.
