title: Ectopic pituitary adenoma with empty sella in the setting of MEN-1 syndrome: detection with 68Ga-DOTANOC PET/CT.
abstract: Patients with multiple endocrine neoplasia type-1 syndromes are known to have neuroendocrine tumors (NETs) involving the pituitary and gastroenteropancreatic region, in addition to the presence of parathyroid abnormalities. In rare instances adenomas in the ectopic pituitary gland have been reported. As pituitary gland and pituitary adenomas are known to express SSTRs, somatostatin receptor scintigraphy can be used for imaging. Somatostatin receptor-based PET/CT imaging using 68Ga-DOTANOC has become a popular noninvasive imaging modality for evaluation of patients with NETs. The application of 68Ga-DOTANOC PET/CT can be extended to multiple endocrine neoplasia type 1 patients, as is evident from this case study.
