title: Inflammatory myofibroblastic tumor of the lung indistinguishable from adenocarcinoma on imaging studies.
abstract: We present the case of a right lung nodule discovered on routine chest x-ray in an asymptomatic 62-year-old man. CT revealed a spiculated nodule in segment 1 of the right upper lobe, 2.2 cm in diameter and without calcification. The nodule showed high focal FDG uptake (SUVmax, 17.8) on PET. Right upper lobectomy was performed under the diagnosis of adenocarcinoma; however, the histopathologic findings were of inflammatory myofibroblastic tumor.
