The distribution of 68Ga-DOTATATE is dependent on cell surface expression of somatostatin receptors, which may be pathologic or physiologic. Osteoporosis circumscripta is the early lytic phase of Paget disease associated with well-defined osteopenia, most commonly seen within the skull on imaging. The appearance has been well demonstrated on 99mTc HDP/MDP bone scans. Here, we present the case of a 76-year-old man with a small bowel carcinoid tumor who underwent staging imaging with 68Ga-DOTATATE PET CT with the incidental finding of osteoporosis circumscripta.
