Herein, we report a case of a 42-year-old woman who presented to hospital with worsening dyspnoea on a background of a 2-week history of typical SARS-CoV-2 symptoms. On admission to the emergency department, the patient was severely hypoxic and hypotensive. A chest radiograph demonstrated a large left-sided pleural effusion with associated contralateral mediastinal shift (tension hydrothorax) and typical SARS-CoV-2 changes within the right lung. She was treated with thoracocentesis in which 2 L of serosanguinous, lymphocyte-rich fluid was drained from the left lung pleura. Following incubation, the pleural aspirate sample tested positive for <jats:italic>Mycobacterium tuberculosis<\/jats:italic>. This case demonstrates the need to exclude non-SARS-CoV-2-related causes of pleural effusions, particularly when patients present in an atypical manner, that is, with tension hydrothorax. Given the non-specific symptomatology of SARS-CoV-2 pneumonitis, this case illustrates the importance of excluding other causes of respiratory distress.<\/jats:p>","DOI":"10.1136\/bcr-2021-243760","type":"journal-article","created":{"date-parts":[[2021,7,26]],"date-time":"2021-07-26T12:41:49Z","timestamp":1627303309000},"page":"e243760","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Tension
