    Spontaneous pneumomediastinum, a rare condition, often affects young adults after exertion or respiratory infections. Diagnosis relies on subcutaneous emphysema and chest X-rays, with conservative treatment usually sufficient.

    Area of Science:

    • Medicine
    • Pulmonology
    • Radiology

    Background:

    • Spontaneous pneumomediastinum is a rare condition with unclear pathophysiology and potentially misleading clinical signs.
    • It frequently affects young adults, presenting with thoracic pain and dyspnea, and may be associated with pneumothorax.

    Purpose of the Study:

    • To report on 7 cases of spontaneous pneumomediastinum over 3 years.
    • To analyze the etiology, clinical presentation, and radiological findings of this condition.
    • To discuss diagnostic and treatment strategies.

    Main Methods:

    • Case series analysis of 7 patients diagnosed with spontaneous pneumomediastinum.
    • Review of etiological factors, clinical symptoms, and radiological evidence (AP and lateral chest views).

  • Evaluation of treatment outcomes, ranging from conservative management to surgical decompression.

    • Main Results:

    • The condition predominantly affected young individuals without gender bias.
    • Common symptoms included thoracic pain and dyspnea; subcutaneous emphysema was often mild and secondary.
    • Precipitating factors included physical exertion and respiratory infections with dyspnea.

    Conclusions:

    • Spontaneous pneumomediastinum diagnosis relies on identifying subcutaneous emphysema and characteristic radiological findings.
    • Conservative treatment (rest, analgesics, sedatives) is recommended for typical benign cases.
    • Severe cases may necessitate mediastinal decompression via supra-sternal drainage.
