Superior mediastinal chordoma presenting as a bilobed paravertebral mass.

Thoracic chordomas are rare, low-grade malignant tumours arising from the notochordal remnants. These tumours are locally invasive and hence have a tendency for frequent local recurrence. This article presents an unusual appearance of a chordoma, as a bilobed tumour involving both the hemithoraxes. Since the treatment of choice for these tumours is complete surgical excision this involved multiple surgical procedures. Copyright 2002 Elsevier Science B.V.
