A case of the Carney triad.
OBJECTIVE
To report a case of mediastinal paraganglioma in the setting of the Carney triad (gastric leiomyosarcoma, extra-adrenal paraganglioma, and pulmonary chondroma).


METHODS
A case of the Carney triad is presented, and the related literature is discussed.


RESULTS
A 47-year-old woman with a history of gastric leiomyosarcoma and retroperitoneal paraganglioma sought medical attention because of progressive shortness of breath. She was found to have a mediastinal mass in the aortopulmonary window. The patient had normal blood pressure and normal urinary catecholamines, but metaiodobenzylguanidine scintigraphy showed an intense uptake in the region of the mass, consistent with paraganglioma. She subsequently underwent resection of the mediastinal mass, and the surgical pathology report indicated paraganglioma.


CONCLUSIONS
Patients with the Carney triad can have multicentric paragangliomas. Metaiodobenzylguanidine scanning may be helpful in the diagnostic workup.
