Inflammatory pseudotumor (IPT) of the heart is rare and of unknown etiology. We present a case of cardiac IPT caused by Listeria monocytogenes that evolved following gastroenteritis in a previously healthy child. L. monocytogenes, known to cause acute invasive infections, has not been reported previously as a cause of cardiac infection in children or of IPT. The literature concerning infectious IPT is reviewed.
