Abstract:
Purpose To explore the CT features of mediastinal cystic mature teratoma. Materials and Methods CT images of 11 patients with pathologically confirmed mediastinal cystic mature teratoma were retrospectively analyzed, distribution within mediastinum, shape of cysts, capsule contents density, walls of cysts and mass cardiovascular interface (MCI) were analyzed. Results All the 11 cases were located in the anterior mediastinum, including three cases confined to the anterior mediastinum, seven cases located mainly within or involving the anterior and middle mediastinum, and one case confined to the anterior inferior mediastinum. Nine cases were round, one case was oval, one case was half round. Seven cases with fat ingredients displayed within the lesions, four cases with fat nodules within the cystic walls;ten cases showed as cysts with significant walls;MCI protrude type in six cases and smooth type in five cases. Fat, hair, keratosis, mucus and other ingredients were found in each cavity in surgery and pathology examination. Conclusion CT features of mediastinal cystic mature teratoma are complex and diverse, but with certain characteristics, thus CT is of great significance in the diagnosis and differential diagnosis of mediastinal cystic mature teratoma.
