Echodense images in the right ventricle (RV) have a wide spectrum of diagnoses, mainly tumors or thrombi. We present the case of a 31-year-old woman in whom an echodense mass in transit in RV suggestive of thrombus was incidentally diagnosed. Venous thromboembolic disease was ruled-out. Cardiac magnetic resonance imaging confirmed the echocardiographic diagnosis. The surgery showed new over old thrombus, and she received indefinite oral anticoagulation. This case illustrates how multimodality in cardiovascular imaging allows accurate assessment of RV masses. The evidence of a thrombus in the RV forces the clinician to rule out mainly immune and hematological diseases.
