What is isthmus thyroid?

Background. The isthmus is the central but relatively very small part of the thyroid gland that connects the right and left thyroid lobes. It is directly anterior to the trachea and is covered by the strap muscles, fascia, and skin in the middle of the neck.

What size should thyroid isthmus be?

The mean volume of the thyroid gland measured by ultrasonography was 32.3 ± 21.0 cm3, and the mean length of the thyroid isthmus was 5.4 ± 3.2 mm.

How big is the Isthmus of the thyroid?

Isthmus measures 0.3 in thickness. Thyroid parenchyma is diffusely heterogeneous in nature. Within this heterogeneous gland, measurement of nodules is considered somewhat arbitrary. In the superior portion of right lobe a relatively hyperechoic portion is seen measuring 1.5 x 1.8 x 1.6 cm.
