pulmonary chondroma
Carney triad
(ECR 2016 Case of the Day). Chest CT scan shows bilateral calcified lung nodules suggesting pulmonary chondromas.
Carney triad
(ECR 2016 Case of the Day). Follow-up CT 6 years later shows further calcification and enlargement of prior lung lesions, as well as appearance of a new nodule in the left lower lobe (arrow).
Carney triad
(ECR 2016 Case of the Day). Coronal CT image shows same findings. These lesions should not be confused with calcified metastases.
Pulmonary chondromas are rare, benign cartilaginous tumors of the lungs, and form part of the Carney triad although they can also arise sporadically.
Epidemiology
Sporadic pulmonary chondromas occur most frequently in middle-aged males, while those associated with Carney triad occur most frequently in young females .
Pathology
Pulmonary chondromas consist entirely of calcified/ossified cartilaginous components. This differentiates them from pulmonary hamartomas, which also contain fat, smooth muscle, epithelial, and stromal elements. They can arise in the lungs, bronchi, trachea, and larynx .
Macroscopic appearance
Well-circumscribed mass with a gray-white cartilaginous appearance .
Differential diagnosis
On imaging consider the differential diagnosis for a calcified lung nodule.
