Primary Pulmonary Paraganglioma Revealed by FDG PET/CT

Primary pulmonary paraganglioma is a rare type of extra-adrenal paragangliomas arising from neuroectodermal-derived paraganglionic tissue. We report herein the case of a 49-year-old woman with a round-like well-defined nodule in the right middle lobe detected by chest CT. FDG PET/CT also revealed this homogeneous nodule with increased FDG accumulation. Finally, the patient underwent right middle lobe resection, and the pathological findings demonstrated the diagnosis of pulmonary paraganglioma.
