| nodule of semilunar valve | A nodule at the centre of the free border of each semilunar valve at the beginning of the pulmonary artery and aorta. Synonym: nodulus valvulae semilunaris, Arantius' nodule, Bianchi's nodule, corpus arantii, Morgagni's nodule. (05 Mar 2000) |
| discordant thyroid nodule | <radiology> Hot on Tc-99m pertechnetate, cold on I-123 or I-131, indicates trapping, but no organification, same work-up as cold nodule (12 Dec 1998) |
| thyroid nodule | A small circumscribed mass of differentiated tissue associated with the thyroid gland. It can be pathogenic or non-pathogenic. The growth of nodules can lead to a condition of goiter, nodular. most nodules appear between the ages of 30 and 50 years and most are benign. (12 Dec 1998) |

| lymph nodule | Lymphatic follicle, one of the spherical masses of lymphoid cells, frequently having a more lightly staining centre. See: solitary lymphatic follicles, Peyer's patches. Synonym: folliculus lymphaticus, lymph nodule, nodulus lymphaticus. (05 Mar 2000) |
