Gallium-67 breast uptake in a patient with hypothalamic granuloma (sarcoid).

An unusual case is presented of bilateral breast uptake of [67Ga]citrate in a patient with a hypothalamic granuloma in the absence of galactorrhea is presented. A possible mechanism for this incidental finding is elevated prolactin levels, as other causes of gallium breast uptake such as drug therapy, and intrinsic breast disease, were not present.
