A Rare Entity Pituitary FDG Uptake; What Should We Expect?

F-18 fluorodeoxyglucos (FDG) positron emission tomography/computed tomography (PET/CT) is widely accepted modality in order to evaluate the cancer patients for staging, restaging and treatment response evaluation.The increasing trend towards application of this modality and growing number of cancer patient population concluded by increased number of FDG PET/CT studies performed. Incidental detection of various importan findings unrelated to the first disease presentation is inevitable and frequent than expected. These findings contribute significant gain in patient management and sometimes prevent second malignancies.One of these secondary findings is incidental pituitary FDG uptake which is a rare situation. The clinical significance of this entity is not well established. This finding may represent malignant involvement rarely or benign causes like pituitary adenoma.
