Primary ectopic intrathoracic goiter in posterior mediastinum: a case report and review of the literature

The ectopic primary intrathoracic goiter is an uncommon tumor that corresponds to a hyperplasia of an ectopic thyroid tissue, that develops in the thorax, distinct from the cervical thyroid gland, which usually exists on its normal aspect. We report the case of a 61-year-old female patient, with the aspects of the radiograph and computed tomography examinations, comparing them with the literature, demonstrating the image aspects, differential diagnosis, possible etiology factors and treatments of the disease.
