Benign mesenchymoma of the mediastinum: a report and review of the literature

Benign mesenchymoma is a rare type of germ cell tumour. An extensive literature search revealed only one described case of mediastinal mesenchymoma in Europe and three cases in Asia. We describe our recent experience of a mediastinal mesenchymoma and present the fascinating imaging and operative findings. The preoperative diagnosis of these lesions remains difficult and therefore surgical resection is recommended.
