title: Venous hemangioma of the anterior mediastinum.
abstract: We report a rare case of venous hemangioma (VH) of the anterior mediastinum in a 56-year-old man admitted to our hospital because of hematemesis. Systemic examinations were performed and chest computer tomography (CT) revealed a 1.5-cm sized small nodule with contrast enhancement in the thymus. Both CT and magnetic resonance imaging (MRI) suggested a solid tumor such as a thymoma or neurogenic tumor rather than a vascular neoplasm. A partial thymectomy including this nodule by video-assisted thoracic surgery (VATS) was performed. Histological examination showed VH. There was no recurrence with no further treatment.
