Vanishing Tumor of the Heart: Very Unusual Location of Left Ventricular Thrombus

Left ventricular (LV) cavity mass is common in clinical practice. Most of the time, it is a thrombus at the LV apex. Nonapical location of mass leads to confusion in the diagnosis with possibilities of tumors or vegetations. Here, we describe a case of LV thrombus in an extremely unusual location. Multimodality images helped us to come to a proper diagnosis. The mass vanished completely from LV cavity with medical management. Our case is unique, as presentation of clot was at very unusual location, only few such cases have been reported in literature. With the help of multimodality imaging, we were able to successfully manage the case conservatively with oral anticoagulation. Left ventricular thrombus is a common complication in patient with ischemic or nonischemic cardiomyopathy. Nonapical location of a thrombus is not only extremely rare but also creates diagnostic confusion. Although echocardiography is a screening imaging modality of choice, magnetic resonance imaging is extremely useful before planning surgical versus nonsurgical treatment option.
