Pneumomediastinum, pneumopericardium and subcutaneous emphysema following acute lymphoblastic leukemia and chemotherapy: A case report.

BACKGROUND: Pneumomediastinum and subcutaneous emphysema are mostly detected in non-malignant conditions such as certain infections, thoracic surgeries, and trauma. Although this condition is asymptomatic in most cases, sometimes it could be symptomatic and may even be lethal in some patients. CASE PRESENTATION: This letter reports a 9-year-old girl with acute lymphoblastic leukemia (ALL) on chemotherapy who developed pneumothorax with the clinical feature of respiratory distress for that a chest tube was inserted immediately. Following the insertion, pneumomediastinum and pneumopericardium developed in the patient. As the next step, a pericardium window was inserted by an expert heart surgeon. During these procedures, all the evaluations for any bacterial or fungal infection were negative. Unfortunately, the patient expired before any further complementary evaluations and it was not clear that the mentioned situation was a result of chemotherapy or ALL. CONCLUSION: Although pneumomediastinum and subcutaneous emphysema are rare in patients with ALL, authors strongly suggest clinicians consider them in any similar patients presenting respiratory signs/symptoms for faster onset of action.
