A 53-year-old woman with pulmonary chondroma. Axial view (a) and (b) mediastinal, bone-window images. CT shows a slightly lobulated, well-defined mass with a characteristic ring calcification in the left lower lobe of the lung. The patient with a large lesion (10.7 cm) showed chest wall adhesion suggestive of malignant infiltration.
