Acute spontaneous pneumomediastinum in a child with Hodgkin's disease and pulmonary fibrosis.

ABSTRACT

A case of acute spontaneous pneumomediastinum in a 13-year-old boy suffering from Hodgkin's disease and pulmonary fibrosis is reported. He was initially treated for Pneumocystis carinii but his respiratory function progressively deteriorated, and fibrosis secondary to bleomycin was suspected. The day before the admission to the Pediatric Intensive Care Unit the patient complained of anterior thoracic pain, and a chest x-ray revealed a left-sided small spontaneous pneumothorax and pneumomediastinum. Although air leak responded initially to conservative treatment, acute tension pneumomediastinum with cardiopulmonary decompensation recurred 6 days later, while the patient was on mechanical ventilation. Treatment with urgent evacuation of the accumulated air via subxiphoid drainage, using an old but ill-defined technique, resulted in complete resolution of pneumomediastinum and significant improvement of the hemodynamic condition.
