Thoracoscopic resection of a mediastinal venous hemangioma: Report of a case

Mediastinal hemangioma is a rare tumor, accounting for 0.5% or fewer of all mediastinal tumors in most reports. We herein report a case of thoracoscopic resection of venous hemangioma in the middle mediastinum. A 48-year-old man was referred to our hospital for dysphagia. A chest computed tomography scan showed the mass to have a smooth surface and heterogeneous contents. Magnetic resonance imaging demonstrated the morphology of the vascular tumor to be a hyperintense mass on a T2-weighted image. Using thoracoscopic surgery, the tumor was completely extirpated and confirmed histologically to be a venous hemangioma. In this case, thoracoscopic surgery provided a satisfactory view and facilitated correct handling for the mediastinal venous hemangioma.
