Development of massive pneumopericardium after intubation and positive pressure ventilation.

Pneumopericardium is a rare complication of chest trauma, mechanical ventilation and cavitating pneumonia. We report a case of a 7-year-old patient with chronic myeloid leukemia who developed massive pneumopericardium immediately after being electively intubated for a diagnostic radiological procedure in the setting of ongoing Enterococcal pneumonia. As intensive care medicine becomes more prevalent in hospitals, we believe that clinicians need to be aware of this uncommon but potentially fatal condition.
