A case of left atrial appendage (LAA) aneurysm misdiagnosed previously as partial pericardial defect is presented. This previously totally asymptomatic young multiparous woman was referred to us because of intermittent sharp chest pain and an abnormal CXR. Complementary imaging modalities revealed a large mass behind the left ventricle causing anterolateral hypokinesis. Although relatively symptomless, because of potential hazardous complications such as paroxysmal supraventricular tachycardia, syncope, sudden cardiac death, embolic phenomena and strangulation, the patient s LAA aneurysm was resected shortly after the confirmation of diagnosis. The postoperative course has been uneventful, and she is currently asymptomatic .
