And as it now turns out this signal is dependent on stimulation from thyroid hormone. In a just-published study scientists now believe that anemia may be the first sign of hypothyroidism, an issue they also document for subclinical hypothyroidism. In the past I have always viewed anemia as a thyroid disrupter.
Pulmonary nodules are small, focal, radiographic opacities that may be solitary or multiple. A classic solitary pulmonary nodule (SPN) is a single, spherical, well-circumscribed, radiographic opacity measuring less than or equal to 30 mm in diameter and is surrounded completely by aerated lung.
A solitary pulmonary nodule (SPN) is the most common radiographic presentation of lung cancer. The imaging characteristics of solitary pulmonary nodules are described and illustrated.The appearance and implications of extension of lung cancer to the pleura are explored.he radiologic work-up of the solitary pulmonary nodule is pursued to facilitate the resection of potentially curable lung cancers and to minimize the resection of benign nodules. Neoplasm can often be strongly suspected or excluded based on the radiologic characteristics of the solitary pulmonary nodule.
