Focal incidental colorectal fluorodeoxyglucose uptake: Should it be spotlighted?

Figure 2 Focal and diffuse intestinal fluorine-18 fluorodeoxyglucose uptake. A 87-year-old man diagnosed with non-small cell lung cancer (squamous cell carcinoma) is depicted. A: Focal (arrow) and diffuse intestinal uptakes are evident. While diffuse uptake may represent physiological activity, a focal hypermetabolic area raises suspicion for a potential pathological lesion; B: Focal uptake is specifically noted in the proximal transverse colon. Subsequent colonoscopy was performed, revealing no significant abnormal lesions.
