What is the size of the parathyroid gland?
The average size as seen sonographically was 3.3 x 2.2 x 1.7 mm and the average gross size was 3.7 x 2.6 x 1.6 mm (length, width, height). The average size of the thyroid lobules assessed sonographically was 2.3 x1.6 x 0.8 mm (length, width, height). Normal parathyroid glands can be identified using high-resolution ultrasonography.
What are parathyroid tumors?
Parathyroid cancer is a cancerous ( malignant) growth in a parathyroid gland. The parathyroid glands control the calcium level in the body. There are 4 parathyroid glands, 2 on top of each lobe of the thyroid gland, which is located at the base of the neck. Parathyroid cancer is a very rare type of cancer. Men and women are equally affected.
