Significance of incidental focal fluorine-18 fluorodeoxyglucose uptake in colon/rectum, thyroid, and prostate: With a brief literature review

Figure 1 A case of malignant incidental focal prostate fluorine-18 fluorodeoxyglucose uptake. A: Focal uptake (black arrow) below the radioactivity of bladder on the maximum intensity projection image of a 76-year-old man diagnosed with non-small cell lung cancer; B: Axial image of fused positron emission tomography/computed tomography showing hypermetabolism (maximum standardized uptake value 8.1) in the left prostate region and histopathologically confirmed as an adenocarcinoma of the prostate gland.
