Thyroid Nodule Demonstrating Itself as Calcified Lung Lesion

Abstract

Multinodular goiter (MNG) is the most prevalent thyroid pathology. Thyroid gland enlarge as a result of MNG, the initial extension is typically outward. After this cervical enlargement, expansion may extend in to the mediastinum. As substernal goiters enlarge within the mediastinum, vascular and visceral structures may slowly became compressed. The most common symptoms of substernal goiter result from compression of the trachea and/ or esophagus and include dyspnea, choking sensation, cough, and dysphagia. Progressive hoarseness and superior vena cava syndrome are less common symptoms. Substernal goiters can remain asymptomatic for many years and it may be diagnosed incidentally. For example, routine chest radiography may reveal a mediastinal mass or tracheal deviation. Many authors have advocated surgical removal of all substernal goiters, even when these goiters are asymptomatic. In this article, we report a case of substernal MNG which demonstrating itself as a nodular calcification on chest X-Ray radiography.
