title: Multisided cardiac hemangiomas mimicking biatrial thrombus: atypically located cardiac hemangiomas of left atrial appendage and right atrium.
abstract: Hemangiomas are rare benign tumors of the heart. Clinical presentation is highly variable according to the location, size, and extension of the tumor. Hemangiomas have been described in all cardiac chambers, but most occur on the right side of the heart and in the left atrium. Although diagnosis is typically made by echocardiography, the definite diagnosis can be made with certainty only from a very careful histopathologic examination. The authors report a case of atypically located hemangiomas originating from the left atrial appendage and right atrium in a 71-year-old woman who presented with ischemic stroke. Transthoracic and transesophageal echocardiography demonstrated an elongated left atrial mass originating in the atrial appendage and extending well into the left atrium to the mitral orifice, as well as a right atrial mass and intense biatrial spontaneous echo contrast. It was unclear whether the masses represented thrombus or an unusually located atrial tumor. Immunohistologic examinations revealed a biatrial cavernous hemangioma with no signs of malignancy.
