False aneurysms (FAs) of the left ventricle are rare. Forty-two cases have been reported in the world literature.1-7 Fibrous tissue forms the wall of an FA, and it appears to be an uncommon result of left ventricular rupture. In the usual case of left ventricular wall rupture, a massive hemo-pericardium results and death follows soon afterward. In cases of rupture resulting in an FA, the hemorrhage that follows is restricted in its extent by the adherent pericardium. The periphery of the localized hematoma becomes organized and new tissue constitutes the fibrous wall of the FA.8 With each heart contraction, blood erupting into the aneurysmal sac causes gradual dilation of the fibrous wall to a huge size, while the size of the hole in the ventricular wall remains unchanged.1,8
We report a case of FA of the left ventricle following septic pericarditis complicating staphylococcal osteomyelitis.
