Recurrent respiratory papillomatosis: False-positive positron emission tomography of an endotracheal mass and a peripheral pulmonary nodule

Andreas Schmid, Bruce Krieger

Research output: Contribution to journalArticle

Abstract

We describe a patient with recurrent respiratory papillomatosis (RRP) who presented with a tracheal mass and a speculated nodule in the right upper lobe (RUL). Both lesions showed increased fluorodeoxyglucose (FDG) uptake on positron emission tomography (PET) although they were found to be benign papillomatosis histologically and cytologically. There has been no progression to malignancy over a 1-year follow up. To our knowledge, this is the first report of a false-positive 18-FDG PET of recurrent respiratory papillomatosis.
