Figure 1.

(A) Horizontal scan of the base of the neck showing a large non-vascular soft tissue mass measuring 6 cm in transverse diameter engulfing and encasing the neurovascular bundle and extending to the cervical oesophagus. (B) Large anterosuperior mediastinal mass measuring 7 cm in transverse diameter engulfing and constricting the superior vena cava and extending to the aortopulmonary window. The mass contains necrotic material. There are also small pleural effusions. (C) After two cycles of CHOP chemotherapy. Significant reduction in tumour mass size with less superior vena cava compression and residual pleural effusions.
