Background:
Coronavirus disease 2019 (Covid-19) is associated with spontaneous pneumomediastinum (SPM) predominantly in those after positive pressure ventilation (PPV) support. Additionally, many cases of venous thromboembolism (VTE) in COVID-19 patients were described. Our case is the first to describe SPM and VTE present on admission in a patient with Covid -19 pneumonia.
Case report:
A 53-year-old man presented to the hospital with escalating dyspnea. Two weeks prior to this visit, he had been evaluated in an ambulatory setting and was started on antibiotics and systemic steroids. In the hospital, this patient was found to be in acute hypoxic respiratory failure and was placed on noninvasive PPV. Diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was confirmed by reverse transcriptase-polymerase chain reaction (RT-PCR) test from nasopharyngeal swab specimen. Chest computed tomography (CT) scan revealed multi-lobar pulmonary emboli (PE) and subcutaneous emphysema with pneumomediastinum. The patient was managed conservatively. He never required closed invasive mechanical ventilation. Subsequent serial imaging displayed the resolution of SPM.
Conclusion:
The association between VTE and COVID-19 has been established. This report brings attention to SPM as an additional important complication of COVID-19, even in patients without pre-existing predisposing pathology or exposure to PPV.
