Anterior mediastinal neoplasms comprise a diverse group of tumors and occasionally manifest as a cystic lesion. We retrospectively reviewed computed tomography (CT) scans in 46 patients with pathologically proved cystic anterior mediastinal tumors. We categorize them into a pure cystic mass and a cystic tumor with a solid portion. In this pictorial essay, the radiologic appearances of cystic anterior mediastinal tumors are described with CT and illustrated with their gross and histopathological findings on resected specimen.
