Herein we depict a very rare case of cardiac hemangioma. A 65-year-old female patient presented with exertional dyspnea and palpitation for a couple of weeks. Her past medical history was unremarkable. She had normal vital signs and physical examination findings. There were no pathological findings in the laboratory analysis. Chest X-ray showed cardiomegaly, particularly in the left cardiac border. Echocardiography revealed a huge well-defined cardiac mass in the anterolateral side of the left ventricle and normal ventricular function without a significant valvular problem. Spiral computed tomography and cardiac magnetic resonance imaging revealed a huge, well-defined solid mass adjacent to the left anterior descending artery and very close to the obtuse marginal branch which was compatible with a benign tumor most probable with hemangioma (Figure 1). Metastasis testing work-up was also unremarkable. En bloc resection of the encapsulated huge solid tumor (12x10.3 cm) was performed by a sharp dissection and electrocautery under cardioplegic arrest with preserving the adjacent coronary arteries. The patient"s postoperative course was uneventful. Histopathological examinations showed a cavernous cardiac hemangioma (Figure 2). The arrows in Figure 2D show the dilated vascular spaces lined by a flat endothelium containing red blood cells, which is the characteristic feature of cavernous cardiac hemangioma.
