[An operated case of ectopic thymic cyst of the posterior mediastinum]

Abstract

We reported an operated case of thymic cyst of the posterior mediastinum, whose common location in the mediastinum is anterior or antero-superior portion. A 58-year-old female was admitted because of the abnormal shadow on a routine chest radiograph. No particular symptoms and physical findings were noticed. The CT scanning and the MR Imaging of the thorax demonstrated the posterior mediastinal mass, which was removed by thoracotomy. The histopathological findings were most consistent with a diagnosis of thymic cyst. No cases of ectopic posterior mediastinal thymic cyst have been described in the recent literature.
