Primary pulmonary pleomorphic adenoma with high uptake of FDG

Primary pulmonary pleomorphic adenoma is a rare tumor. Although it is a tumor with benign histology, it has potential to recur or metastasize. Most patients with pulmonary pleomorphic adenomas have symptoms and signs of chronic bronchial obstruction. Some are asymptomatic, presenting as an incidental finding on chest X-ray. Treatment of choice is complete surgical removal. We report our experience of FDG-PET in a patient with primary pleomorphic adenoma. The tumor was represented with high FDG uptake with maximal standard uptake value (SUVmax) of 8.4. It could not be differentiated from a malignant lesion by FDG-PET. This patient received surgical removal of the tumor. No recurrent or metastatic disease noted 26 months following the surgery.
