3P's of Wermer/MEN1 Syndrome on 68Ga-DOTANOC PET/CT Scan.
Wermer/MEN1 syndrome is composed of the triad of pancreatic, pituitary, and parathyroid (3P's) tumors. We describe the Ga-DOTANOC PET/CT findings of a 43-year-old man, which revealed the classic 3P's of MEN1 syndrome with somatostatin receptor expression. The patient further underwent surgery for parathyroid lesions, which were suggestive of adenomas.

Tumor-Induced Osteomalacia Caused by a Parotid Basal Cell Adenoma Detected by 68Ga-DOTANOC PET/CT.
Tumor-induced osteomalacia is a rare paraneoplastic syndrome, usually caused by small benign mesenchymal tumors. The tumors most arise within the extremities, whereas occurrence within the parotid gland is quite rare. A 54-year-old woman who presented with bone pain and muscle weakness for 2 years was clinically suspected of having tumor-induced osteomalacia. A Ga-DOTANOC PET/CT was performed for localization of the causative tumor. The images demonstrated intense radiotracer accumulation in a soft tissue nodule in deep lobe of the right parotid gland. Subsequent surgical resection and pathologic analysis confirmed the diagnosis of parotid basal cell adenoma.

Detection of paranasal ectopic adrenocorticotropic hormone-secreting pituitary adenoma by Ga-68-DOTANOC positron-emission tomography-computed tomography.
Ectopic adrenocorticotropic hormone (ACTH)-secreting tumors account for approximately 10% of Cushing's syndrome (CS). We present an extremely rare case of a patient with CS caused by an ectopic ACTH-secreting pituitary adenoma (EAPA) of the ethmoid sinus. The tumor was identified by positron-emission tomography-computed tomography (PET/CT) using the somatostatin receptor analogue Ga-68-DOTANOC. Transnasal endoscopic resection was performed and the patient showed significant clinical improvement with normalization of the endocrine pituitary axis. Immunostaining showed a somatostatin receptor 2 and 5-positive ACTH-producing adenoma. In patients with ectopic ACTH secretion, Ga-68-DOTANOC-PET/CT may play an important role in the localization of EAPA. Transnasal endoscopic resection is the therapy of choice.
