Introduction:
Spontaneous pneumomediastinum (SPM) is a rare affection in general population. Only few cases have been reported during this ongoing global pandemic of Coronavirus-2019 (COVID-19). The ethipathogeny of this complication is poorly understood.
Observations:
we reported ten cases of SPM complicating coronavirus pneumonia. There were six me and four women. Age varies from 32 to 66 years. Pneumonia was severe for all cases defined by a bloo oxygen saturation < 90% on admission. All patients were hospitalized in intensive care unit and treated by high-flow oxygen for nine patients and non-rebreather masks for one patient. Repeated chest computed tomography (CT) scan showed resolution of the pneumomediastinum and appearance of signs of pulmonary fibrosis for four cases.
Conclusions:
Chest CT scan must be performed in front of any sudden deterioration in respiratory status of patients with COVID-19 pneumonia to not miss mechanical complication such as SPM. This complication seems to be associated with severe forms of COVID-19.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
