A 62-year-old woman with pulmonary chondroma. Mediastinal window images are shown. Computed tomography (CT) shows a slightly lobulated, well-defined nodule in the left upper lobe of the lung. (a) Precontrast axial CT scan shows an inhomogeneous soft tissue density nodule (19 HU). (b) Postcontrast axial arterial phase scan. (c) Postcontrast coronal arterial phase scan. (d) Postcontrast axial venous phase scan. The lesion shows a slight enhancement of 10 HU (arterial) and 14 HU (venous).
