Core Tip

Core Tip: We herein present a rare case of rectal dual-source grade 2 neuroendocrine tumors with a pituitary growth hormone-secreting tumor that caused acromegaly and diabetes. The rarity of this combination makes an accurate diagnosis difficult to achieve. The correct diagnosis can be obtained by using 18F-ALF-NOTATATE-positron emission tomography–computed tomography and magnetic resonance imaging combined with pathological analysis.
