Lingual thyroid imaging.

Abstract

Lingual thyroid is the most frequent benign mass found at the junction of the anterior two-thirds and posterior one-third of the tongue. MR has become the best non-invasive technique to make the diagnosis because it allows multiplanar imaging and provides the best soft tissue definition. Aberrant primitive vascular supply is often present and therefore angiography remains necessary because precise knowledge of the vascular supply is mandatory prior to embolisation, ligation, or operation.
