[Multilocular thymic cyst]

Abstract

We describe a case of multilocular thymic cyst with severe acute inflammation. A 23-year-old man was admitted to our hospital with a sudden onset of chest pain and high fever. A computed tomography scan showed multilocular cystic lesion at anterior mediastinum. We resected the tumor with the thymus by median sternotomy. Macroscopically, the mediastinal mass showed thick-walled multiloculated cavities filled with turbid yellow fluid. Histological examination revealed that the tumor was a multilocular thymic cyst which is reported by Suster.
