Mediastinal hemangiomas are relatively rare, accounting for 0.5% or less of all mediastinal tumors, and they are difficult to diagnose preoperatively. A 61-year-old female was referred to the Department of Cardiology of our hospital due to electrocardiogram abnormalities noted during a health examination. Coronary CT angiography incidentally revealed a nodule, 1.3 cm long, in the anterior mediastinum. We suspected it to be a thymoma because of the presence of enhancement on CT, and performed thoracoscopic surgery through the left pleural cavity. The tumor was dark-red and elastic-soft, and we resected it with part of the left lobe of the thymus. The tumor was diagnosed as a cavernous hemangioma histopathologically. Cavernous hemangioma should be considered as a differential diagnosis of a mediastinal tumor.
