Fig.50. Different shapes of the thyroid gland. Reconstructed two-dimensional images of the thyroid gland. A - Anterior view - projection on the frontal plane. B - Right lateral view - projection on the sagittal plane. 1 - Normal. Thyroid gland has two lobes connected by the isthmus. 2 - Congenital abnormality - lobulate thyroid gland. 3 - Con-genital abnormality - aplasia of the left lobe. 4 - Flat-type thyroid shape. 5 - Congenital abnormality - hypoplasia of the right lobe. 6 - Cone-shaped thyroid gland.
