title: [A case of supramediastinal neurinoma: its operative approach (via supraclavicular route) and radiographic findings (target sign)].
abstract: A 76-year-old female with supramediastinal tumor was admitted. CT scan showed central high density area surrounded by low density area and MR imaging emphasized the same concentric circle. This concentric circle pattern on CT scan and MR imaging is called "Target sign", which is known as characteristic radiographic finding of neurinoma. Therefore we could diagnose her case as mediastinal neurinoma preoperatively. She underwent operation through the supraclavicular approach and the tumor was completely resected. By incising the skin through the modified left hemi-collar incisional line and cutting the clavicula at its central part, we could ensure a good operative field and safely performed this operation without mid-sternotomy or thoracotomy. The supraclavicular approach for the operation of supramediastinal tumor is useful.
