Pneumomediastinum as a primary manifestation of COVID-19: A case report

Abstract

Introduction: Pneumomediastinum is a rare complication that occurs in patients with Pneumonia caused by COVID-19 and is more frequent in patients with ARDS that may or may not be related to the use of invasive mechanical ventilation. Pneumomediastinum is an indicator of clinical deterioration with potentially threatening consequences for the patient. Method: We described a case report of a 23-year-old man with Pneumomediastinum, infected with COVID-19 in conditions of respiratory failure due to interstitial pneumonia. Case presentation: A 23-year-old man, who had no pre-existing health conditions presented to the Infectious Diseases service with complaints of difficulty in breathing, dry cough, chest pain, muscle pain, joint pain, loss of taste, sore throat, pronounced body weakness, diarrhea. Symptoms started 11 days ago. On admission the patient refers that he doesn’t suffer from any other disease. The patient was not vaccinated against COVID-19. At the time of admission to the hospital, the objective examination revealed cervical subcutaneous emphysema and harsh respiration in both lungs. The nasopharyngeal swab test (RT-PCR) for Covid-19 was positive from the Institute of Public Health. The CT scan of the chest confirmed the presence of pneumomediastinum major, subcutaneous emphysema and bilateral ground glass opacities. Conclusion: Pneumomediastinum is a rare complication of pneumonia caused by Covid-19 in which the etiopathogenesis consists of severe pulmonary involvement that may or may not be affected using invasive mechanical ventilation. Timely diagnosis of pneumomediastinum in patients with Covid-19 would prevent the occurrence of life-threatening complications. Keywords: Covid-19, pneumomediastinum, ARDS, Macklin effect, vaccine.
