Pneumomediastinum Associated with Pneumopericardium and Epidural Pneumatosis

الملخص EN

Spontaneous pneumomediastinum is a relatively rare benign condition.

It may rarely be associated with one or combination of pneumothorax, epidural pneumatosis, pneumopericardium, or subcutaneous emphysema.

We present a unique case with four of the radiological findings in a 9-year-old male child who presented to our emergency department with his parents with complaints of unproductive cough, dyspnea, and swelling on chest wall.

Bilateral subcutaneous emphysema was palpated on anterior chest wall from sternum to midaxillary regions.

His anteroposterior and lateral chest radiogram revealed subcutaneous emphysema and pneumomediastinum.

His thorax computed tomography to rule out life-threatening conditions revealed bilateral subcutaneous, mediastinal, pericardial, and epidural emphysema without pneumothorax.

He was transferred to pediatric intensive care unit for close monitorization and conservative treatment.

He was followed-up by chest radiographs.

He was relieved from symptoms and signs around the fifth day and he was discharged at the seventh day.

Diagnosis of pneumomediastinum is often made based on physical findings and plain radiographs.

It may not be as catastrophic as it is seen.

Close cardiopulmonary monitorization is mandatory for complications and accompanying conditions.

Most patients with uncomplicated spontaneous pneumomediastinum respond well to oxygen and conservative management without any specific treatment.
