Transthoracic echocardiography showed normal left ventricular systolic function with an ejection fraction of 68%, normal valve function, and a well-defined mass adjacent to the posterior and inferior cardiac walls of the left ventricle. Transesophageal echocardiography revealed a solid mass with a partial honeycomb structure adjacent to the posterior cardiac wall of the left ventricle. A contrast-enhanced computed tomography (CT) scan revealed a solid mass (115 × 79 × 30 mm) with heterogeneous enhancement adhering to the posterior wall and arterial inflow into the mass. Angiography of the right coronary artery revealed mild contrast agent pooling in the venous phase, suggesting the presence of a nutrient vessel in the mass. Cytological examination and histopathological diagnosis after CT-guided needle biopsy revealed Class III tumor with no malignant findings. Considering the challenges in diagnosis with the current tests and the potential risk of cardiac tamponade caused by repeated biopsies, we adopted a policy that tumorectomy should be performed to elucidate the diagnosis.
