Incidental Finding of PSMA-avid Pulmonary Sclerosing Pneumocytoma on 68 Ga PSMA PET-CT

Primary pulmonary sclerosing pneumocytoma (PsP) is an unusual benign pulmonary tumor with low malignant potential. Clinical presentation may sometimes imitate more serious conditions. We described a case of newly diagnosed prostate cancer with a PSMA-avid, well-circumscribed lesion in the right lung in 68 Ga PSMA PET-CT, initially mimicking a metastatic lesion. Following histopathologic examination, the case was confirmed as a rare pulmonary tumor, PsP. We declare the first reported case in the literature demonstrating PSMA expression in PsP.
