Uncommon Case of Intrapericardial Nontyphoidal Salmonella Infection in a Preterm Baby Presenting As a Cardiac Tumor.

We report a case of an intrapericardial infection resulting from Salmonella Tennessee in a 2-month-old baby, which, upon initial presentation, was masked by a cardiac tumor. The diagnosis was confirmed after successful surgical resection of the mass. Transmission of the infection may have occurred between mother and child in utero, rendering this case extremely unusual.
