Pak Armed Forces Med J Jan ;70(Sup-4):S909-11.

Thymic CYSTs of the mediastinum are rare. It has been reported that their incidence is between 1 to 4.8%. They usually present as an asymptomatic mediastinal mass and are mostly found incidentally. This study reports a rare presentation of a mediastinal thymic CYST in a 50-year-old male, whose chronic right sided chest pain prompted him to visit a local hospital where his chest x-ray revealed a large mediastinal mass at the right cardiophrenic angle. His chest CT revealed a large multilocular hypodense cystic lesion that was resected completely by median sternotomy. On Histopathological examination, Hassals corpuscles confirmed the diagnosis of thymic CYST.
