Abstract: | A 47-year-old female with a history of untreated hypertension and diabetes mellitus was referred because of a left ventricular echocardiographic mass with congestive heart failure. At the time of admission, she had already had a cardio-embolic stroke with loss of recent memory and slight paralysis of the right upper arm. It was difficult to distinguish between thrombus and tumor. However, her clinical condition required surgical resection as soon as possible. We performed cardiac CT to evaluate the coronary arteries and to scan the mass at the left ventricular apex. This CT evaluation revealed another mass at the left atrial appendage. Thus, these two masses were highly suggestive of thrombi. Subemergency surgical resection of the two masses and a part of the myocardium at the left ventricular apex was successfully performed. The pathological results showed that both the mass in the left ventricular apex and the mass in the left atrial appendage were thrombi, and the myocardial disarray confirmed the echocardiographic diagnosis as hypertrophic cardiomyopathy. |
