Primary cervicothoracic thyroid paraganglioma.

A 44-year old man presented with increased shortness of breath. A chest X-ray revealed a widening of the mediastinum (Fig. 1a). Magnetic resonance imaging demonstrated a right paratracheal tumour (Fig. 1b, c). Rotational arteriography showed that the right thyrocervical artery was supplying the mass (Fig. 1d). He underwent a right cervical incision and thoracotomy resection of the mass. Histology showed thyroid paraganglioma.
