Abstract
Fig. 1a. Radiograph frontal view showing homogeneous opacity lesion in the right upper and mid zone with broad base towards mediastinum. The lesion is causing shift of mediastinum and trachea to the contralateral side and compressing the trachea just above the carina (arrow head). The lesion is extending above the clavicle (cervico-thoracic sign) and causing erosion of posterior ends of third and fourth ribs (Long arrow). b-d) Contrast enhanced CT scan axial section mediastinal window showing heterogeneously enhancing mass lesion in the right posterior mediastinum extending to middle mediastinum causing compression & antero lateral displacement of the trachea (arrow head in fig. b) and main bronchi. There is a soft tissue lymph node mass in the right axilla (arrow in fig b) and multiple small foci of calcification within the mediastinal mass (black arrows in fig c). The vertical extension can be better appreciated on coronal reformatted image (d)
