What condition is associated with falsely high uptake of glucose in tumor imaging?

The condition associated with falsely high uptake of glucose in tumor imaging is sarcoidosis. In this disease, granulomas form due to an abnormal immune response, which can lead to increased metabolic activity and glucose uptake in affected tissues. This elevated uptake can mimic tumor activity during a PET scan, potentially complicating the distinction between benign and malignant lesions.

For others listed, bronchitis, asthma, and chronic cough do not typically result in the formation of granulomas or significant glucose uptake that could interfere with tumor imaging. Instead, these conditions are more related to inflammation and may not contribute to increased PET scan signals as prominently as sarcoidosis does. Thus, it is important for radiologists and medical professionals to recognize sarcoidosis when interpreting PET scans for accurate differentiation of potential malignancies.
