18 F-Labeled Fluoro-2-Deoxyglucose Positron Emission Tomography and Computed Tomography in a Large Pulmonary Sclerosing Pneumocytoma with Contralateral Lung Metastasis

Pulmonary sclerosing pneumocytoma is an exceedingly rare neoplasm of the lung. These tumors are usually slow growing with a benign disease course but can easily be mistaken for carcinoid tumors or adenocarcinoma in cytology or histopathology specimens. Rare occurrences of metastases have been reported in the literature making F-labeled fluoro-2-deoxyglucose positron emission tomography and computed tomography useful for the evaluation of these tumors.
