Pulmonary alveolar proteinosis (PAP) is a rare lung disease characterized by an accumulation of periodic acid-Schiff positive lipoproteinaceous material in the alveolar space. A 67-year-old smoking man was diagnosed with PAP in December 2003. We present the case of PAP with mild and heterogeneous accumulation of F-18 fluorodeoxyglucose (FDG) in both lungs shown on the combined F-18 FDG positron emission tomography and computed tomography. Increased rates of glucose utilization by the inflammatory cells involved in the pathogenesis of PAP might explain the mildly increased pulmonary F-18 FDG uptake we observed.
