Left ventricular pseudoaneurysms are an uncommon complication of myoca
rdial infarction and need urgent surgical repair. Though it is critica

misdiagnosed. We report an abnormality which may be mislabeled a pseu
doaneurysm which we term a pseudo-pseudoaneurysm. The approach to accu
rate diagnosis of pseudoaneurysms is discussed.
