title: Diagnosis of posterior mediastinal goiter by computed tomography.
abstract: Although radionuclide examinations are usually diagnostic for evaluating mediastinal goiters, false negative examinations do occur, and the diagnosis may not be suspected based on clinical or radiographic features. In such a setting, computed tomography (CT) may demonstrate both anatomic and physiologic evidence of thyroid mass, providing useful diagnostic information. We report a case in which CT derived data aided in an early diagnosis of mediastinal gioter.
