The coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease mainly affects respiratory system. Its common clinical findings include fever, cough and shortness of breath. Characteristic radiological features of the disease include peripherally distributed, bilateral ground-glass opacities, predominantly involving the lower lung zones. In this report, we present a case of COVID-19 disease presenting with spontaneous pneumothorax. A 26-year male patient was admitted to the Emergency Department with fever, dry cough, shortness of breath and right-sided chest pain. Radiographic imaging of the patient revealed pneumothorax on the right and peripherally distributed non-homogenous opacification. The patient underwent right lateral tube thoracostomy. COVID-19 was diagnosed on testing of nasopharyngeal swab. In conclusion, spontaneous pneumothorax is one of the rare presentations of COVID-19 pneumonia and should be kept in mind in patients presenting with shortness of breath and chest pain.

Key Words: Spontaneous pneumothorax, Corona, pneumonia.


The coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).1 SARS-CoV-2 is a member of the coronaviridae family and contains a single stranded RNA.1,2 In December 2019, a new case of coronavirus infection occurred in Wuhan, China.1 The new coronavirus was identified on January 6, 2020 and labelled as 2019-nCoV.3 Worldwide, more than 6, 057, 853 cases of COVID-19 and 371,166 COVID-19-related deaths have been reported till 1st June 2020.4

The clinical features of mild COVID-19 include symptoms common to other viral infections,1 while clinical features of severe COVID-19 include pneumonia, acute respiratory distress syndrome (ARDS) and shock.5

Chest radiographs show low-density pneumonia, which mostly involves bilateral mid-lower zones. In computed tomography (CT), the most common radiological finding is ground-glass appearance.6 In this report, we present a case of COVID-19 pneumonia, who was admitted with spontaneous pneumothorax and recovered completely.


A 26-year man was admitted to the Emergency Department (ED) with the complaints of fever, cough, shortness of breath, and right-sided pleuritic chest pain. He was in usual state of health three days back when he started having fever with dry cough. He denied body aches and flu-like symptoms. He took paracetamol for fever. His condition did not get better and he started having right-sided pleuritic chest pain one day before presenting to ED. His past medical history was unremarkable. He did not smoke and there was no travel history in recent past. He was in respiratory distress on presentation. Blood pressure was 110/70 mmHg, pulse 124/min, respiratory rate 30/min, temperature 38.5°C, and oxygen saturation (SpO2) with finger probe was 88% on room air. Breathing sounds were decreased on the right side and rest of the examination was unremarkable. Arterial blood gases were done immediately, which revealed a pH of 7.45 with a partial pressure of carbon dioxide of 22 mmHg, partial pressure of oxygen of 66 mmHg, and arterial oxygen saturation of 86% on room air. On chest radiograph, he was found to have right-sided pneumothorax (Figure 1).

In blood tests, total leucocyte count was 12.06×103/uL, lymphocytes 1.59×103/uL, hemoglobin 15.4 g/dL, hematocrit 42.4%, platelets 188×103/uL creatinine 0.91 mg/dL, alanine aminotransferase 13 U/L, aspartate aminotransferase 11 U/L, lactate dehydrogenase 150 U/, and procalcitonin was 0.043 ng/ml. Patient was put on mechanical ventilation in ED due to hypoxemia and respiratory distress. He underwent right lateral tube thoracostomy for pneumothorax and was connected to thoracic suction. The patient was hospitalised with suspicion of COVID-19 and supportive medical therapy was started. On nasopharyngeal swab, SARS-CoV-2 was detected in the polymerase chain reaction (PCR). He was stared on intravenous hydrocortisone and oral hydroxychloroquine. His repeat chest radiograph after 12 hours showed complete resolution of right-sided pneumothorax with expansion of right lung and right-sided peripherally located non-homogenous opacification (Figure 2).

On second day, leak persisted but patient gradually got better and on third day, was extubated successfully. Other treatment was continued. On chest radiograph, right lung was fully expanded but right-sided opacification continued. Thoracic suction was stopped and he was connected to an underwater seal bottle. Patient was shifted out of intensive care unit and kept in a negative pressure room. On fifth day, he was found to have no leak and right lung was completely expanded. Thoracostomy tube was clamped for six hours and repeat chest radiograph showed no pneumothorax, so tube was removed. Patient was discharged in stable condition on eighth day and advised to remain in home isolation for another week. His repeat nasopharyngeal swab after one week of discharge did not detect SARC-CoV-2. His right lung remained expanded on one week follow-up.


Clinical presentations of COVID-19 have ranged from asymptomatic or mild symptoms to severe illness, respiratory distress syndrome and mortality. Common presenting symptoms include fever, cough, and shortness of breath.  Other symptoms, such as malaise and respiratory distress, have also been reported. Huang et al. reported fever as the most common symptom followed by cough, myalgia and fatigue.1 Headache, sputum production, and diarrhea were reported as rare clinical presentations of this disease. All patients with COVID-19 pneumonia have abnormal lung imaging; and ground-glass opacities are the most common radiographic findings, especially on computed tomography (CT) scan. Pneumothorax has been reported as a very rare presentation of COVID-19.

Aydin et al. reported spontaneous pneumothorax in a young patient with COVID-19.7 There were bilateral irregular consolidation areas. There was no underlying lung disease that would have predisposed the patient to pneumothorax.7 Salehi et al. investigated imaging findings in 919 COVID-19 positive patients and detected ground-glass densities in 88% of cases. None of them developed pneumothorax.8

In severe acute respiratory failure syndrome, sudden alveolar pressure increase may cause interstitial emphysema and air leak, leading to the development of mediastinal emphysema.9 In a descriptive study, Chen et al. described a case of COVID-19 infection, presenting with spontaneous pneumothorax.10

In this study, we presented a 26-year man with no underlying structural lung disease. He presented with COVID-19 pneumonia and pneumothorax. Pneumothorax may develop in COVID-19 pneumonia due to alveolar damage. This can cause increased mortality and morbidity. During this pandemic, every patient with dyspnea and fever should be screened for COVID-19.

A written informed consent has been obtained from the patient to publish data related to this case.
