title: 68Ga DOTATATE PET/CT of Synchronous Meningioma and Prolactinoma.
abstract: Ga DOTATATE PET/CT in noninvasive characterization of synchronous pituitary neoplasm and meningioma in a 38-year-old man is illustrated. The patient presented with an MRI-detected lobulated enhancing sellar-suprasellar mass with erosion of bony sella measuring 4.5 × 3.5 × 3.4 cm (with differential diagnosis with germ cell tumor) and a right parafalcine mass (2.7 × 2.6 cm) suggesting meningioma. Ga DOTATATE PET/CT demonstrated intense uptake in both lesions, suggesting the sellar mass to be pituitary macroadenoma. The finding of high serum prolactin and normal LH, FSH, cortisol, and testosterone levels suggested diagnosis of prolactinoma, and the patient was started on cabergoline.
