CTICasesCarney Triad with Extra-Adrenal Paraganglioma and Pulmonary Chondromas
Imaging findings
Frontal chest radiograph reveals multiple well-defined, calcified nodular lesions in the lungs. Contrast-enhanced MRI of the spine demonstrates a lobulated, vascular extra-dural soft tissue mass in the cervical region, representing a recurrent extra-dural paraganglioma. Chest CT confirms the presence of multiple pulmonary chondromas showing characteristic dense calcifications, including lesions in the left apex and right lower lobe.
Key takeaways
Carney triad is a rare syndromic association classically comprising gastrointestinal stromal tumors, pulmonary chondromas, and extra-adrenal paragangliomas. Pulmonary chondromas are benign mesenchymal neoplasms that often present as well-circumscribed, densely calcified or ossified lung nodules. Recognition of the combination of paragangliomas, which can occur in extra-dural or mediastinal locations, and calcified lung nodules should prompt consideration of this syndrome.
