Case study observes intense 18F-FDG uptake in pulmonary nodule in a man with cancer, suggesting malignancy. This raises important diagnostic considerations in imaging interpretations.
A 78-year-old man with hormone-sensitive metastatic prostate cancer underwent chest CT, which revealed a gradually enlarging pulmonary nodule in the left upper lobe, suggestive of lymphangitic metastasis. To further evaluate the lesion, both 18F-FDG and 18F-PSMA-1007 PET/CT were performed. The lesion showed intense FDG uptake but relatively low PSMA uptake, raising the suspicion of a primary lung malignancy. Histopathologic examination after wedge resection confirmed pulmonary tuberculosis.
