CT and MRI findings of developmental abnormalities and ectopia varieties of the thyroid gland.
Ectopic thyroid tissue may be observed anywhere from the tongue base to the     lower neck. It is rarely seen in the mediastinum and abdominal cavity. Computed     tomography and magnetic resonance imaging are very sensitive for detection and     localization of ectopic thyroid tissue. This pictorial essay presents the     radiological characteristics of developmental abnormalities and ectopia     varieties of the thyroid gland.
