The cranial lesion (M) is located in the anterior cervical space; on CT it appears homogeneously hypodense with sharp margins and a dumb-bell shape. The waist of the lesion (arrows) probably corresponds to a defect of the thyrohyoid membrane, through which it reaches the paraglottic space.
 
The caudal lesion (N) lies in the retropharyngeal space; it is in close contact with the left lobe of the thyroid gland (arrows) and the oesophagus (arrowheads), both anteriorly displaced. Though some fat density areas may be detected (asterisks), the lesion mainly displays a fluid density; it is subdivided by relatively thick septa and bordered by an enhancing peripheral rim.
 
On macroscopic examination whitish areas correspond to chondroid metaplasia; they are surrounded by yellowish fat tissue.
