Therefore, the role of radiology is of the utmost importance in the initial evaluation and staging of thymic mediastinal masses. The objective of this study was to elaborate a retrospective analysis of the cases of thymic lesions that underwent surgery at the Cardiothoracic Department of Centro Hospitalar Vila Nova de Gaia/Espinho (CHVNG/E), from January 2013 to December 2016, illustrating their main radiologic findings with computed tomography (CT) images. During the studied time period, 35 patients were diagnosed with thymic lesions including: 14 thymomas (40%), 9 thymic cysts (26%), 4 thymic hyperplasias (11%), 3 thymic carcinomas (9%), 2 thymolipomas (6%), 2 lymphomas (6%) and 1 neuroendocrine tumour (3%). The mean age of the sample was 60 years, ranging from 23 to 88 years, with a predomi- nance of the female sex (69%). In this article, 11 CT images and 1 thoracic x-ray are presented to illustrate the common imaging ...Continue Reading
