[Use of 18F-FDG-positron emission tomography in presurgical evaluation of nonspecific or suspectious adrenal masses in non-oncologic patients].

Background And Objective: Our purpose was to assess the utility of 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) in pre-surgical characterization of adrenal masses. These masses were incidentally discovered in non-oncologic patients or during the study of endocrine hormone overproduction. These nodular lesions showed nonspecific or suspicious radiological features in the imaging tests routinely performed (CT and/or MRI).

Radioiodine therapy for multinodular goiter.

Treatment options for large, compressive goiters are currently limited to surgery and radioiodine administration. Classically, the first-line option has been surgery, with radioiodine therapy being reserved as an alternative treatment in patients with high surgical risk. We describe the case of an 81-year-old woman with a large, compressive multinodular goiter and hyperthyroidism, substernal extension and associated co-morbidity, contraindicating surgery.
