The British Society of Thoracic Imaging (BSTI) has published clear guidance on the classification of chest X-ray (CXR) findings in coronavirus disease 2019 (COVID-19) patients, which are summarised in four main categories: COVID-classical, COVID-indeterminate, COVID-normal, or non-COVID. We report the case of a 34-year-old lady who is otherwise fit and well. She presented with typical COVID-19 symptoms requiring supplemental oxygen, with normal CXR and COVID-19 reverse transcriptase-polymerase chain reaction (RT-PCR) swab on admission. Her condition deteriorated after 24 hours with severe hypoxia requiring up to 60% oxygen. Repeat CXR was normal, which was followed by computed tomography pulmonary angiogram (CTPA) that ruled out pulmonary embolism; however, CTPA confirmed multi-lobar pneumonia consistent with COVID-19. The patient was admitted to the intensive care unit for non-invasive ventilation (NIV) and ongoing care. Extended respiratory screening confirmed positive COVID-19 antibodies and positive adenovirus swabs. The patient also developed COVID-19 related hepatocellular injury and myocarditis in the absence of other causes. These were treated by a multidisciplinary team, and the patient achieved full recovery after three weeks. This case highlights the fact that normal CXR does not rule out COVID-19 pneumonia even in the severely hypoxic patient requiring NIV. Also, it is important to investigate for other potential causes of hypoxia in a deteriorating patient, such as pulmonary embolism and non-COVID causes of pneumonia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
