PY - 2015 T2 - Fishman's Pulmonary Diseases and Disorders, 5e AB - Mediastinal masses represent a diverse collection of tumors, vascular abnormalities, and cysts arising from and associated with each of the organs and structures found within the thorax.1–4 Cystic lesions account for up to 25% of reported mediastinal masses.1,3–5 These cysts may be congenital or acquired or may represent cystic degeneration of a previously solid tumor. In this chapter, we focus on congenital cystic lesions within the mediastinum, specifically addressing the spectrum of foregut cysts including bronchogenic cysts, esophageal duplication cysts, and neurenteric cysts. Together they constitute up to 9% of all primary mediastinal masses. In addition, we briefly consider simple cysts arising from the thymus, pericardium, and thoracic duct. Many other solid mediastinal neoplasms (dermoids, teratomas, thymomas, parathyroid adenomas, and thyroid goiters) may present with cystic components. These lesions are discussed in Chapter 82.
