To the Editor.—In the December 1991 issue of the Archives, Radkowksi et al1 discuss the absolute need for nuclear scanning in patients with midline cervical cysts. We are concerned with the fact that ultrasound is not included in the workup of the patients. Ultrasound is useful in identifying the mass, its internal architecture, and the presence of other subsidiary masses. It also characterizes the appearance, size, and echogenicity of the thyroid gland.

It is our belief that ultrasound should be the first study performed.2 If a normally positioned thyroid gland is seen and a mass superior to it in the midline has the typical appearance of a thyroglossal duct cyst (eg, echo-free cyst or a cyst with low-level echoes) then further investigation is not necessary. If, however, normal thyroid tissue is not seen and the ultrasound of the mass has the echogenicity consistent with thyroid tissue then further
