title: Cardiac hemangioma of the left atrial appendage: CT and MR findings.
abstract: Cardiac hemangiomas are rare, benign primary cardiac neoplasms. We describe the CT and MR imaging findings of a cardiac hemangioma arising from the myocardium of the left atrial appendage and protruding into the pericardial cavity. The tumor displayed homogenous density on CT, heterogeneous signal intensity on MR, and inhomogeneous enhancement after intravenous contrast administration. The hemangioma in this case was difficult to differentiate from other myocardial or a pericardial tumor.
