Background. Mediastinal hemangioma is a rare tumor and difficult to diagnose preoperatively. Case. A 30-year-old woman presenting with a fever and severe chest pain was referred to our hospital for treatment of a giant posterior mediastinal tumor. Chest radiography on admission revealed opacification of the left hemithorax. Chest computed tomography showed a left posterior mediastinum tumor measuring 100×65 mm. Chest magnetic resonance imaging showed was low signal intensity on T1-weighted imaging and high signal intensity on T2-weighted imaging. Lymphangioma was suspected by a percutaneous computed tomography-guided biopsy. The tumor was excised by thoracoscopic surgery. Immunohistochemical staining showed that the tumor cells were positive for desmin and CD34, and the tumor was diagnosed as hemangioma. Conclusion. We experienced a case of a giant posterior mediastinal hemangioma presenting with left lower atelectasis excised by thoracoscopic surgery.
