Goitre (Calcified Thyroid Nodule; Rad)	

Fig. 23.37 Goitre: calcified thyroid nodule. This AP film of the thoracic inlet shows the typical appearance of a large calcified thyroid nodule which is slightly displacing the trachea to the right side. Most goitres, however, do not show calcification. Calcified goitres are usually benign but may be malignant.
