PY - 2023 T2 - Fishman’s Pulmonary Diseases and Disorders, 6e AB - Mediastinal masses encompass a diverse spectrum of solid tumors, vascular abnormalities, and cysts, arising from and associated with each of the structures found within the mediastinum.1–4 Cystic lesions account for up to 25% of reported mediastinal masses.1,3–5 These cysts may be congenital or acquired, or they may represent cystic degeneration of a previously solid tumor. In this chapter, we focus on congenital cystic lesions within the mediastinum, specifically addressing foregut cysts including bronchogenic cysts, enterogenous (esophageal duplication) cysts, and neurenteric cysts. Together, they constitute up to 9% of all primary mediastinal masses. We will also 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 separately in Chapter 82. SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/19 UR - accessmedicine.mhmedical.com/content.aspx?aid=1195009214 ER -
