On physical examination, the cardiopulmonary system was unremarkable. Chest X- ray revealed a rounded calcified cystic mass along the left cardiac border.

Histologic examination of excised lesion shown cystic wall including dense fibrous connectivetissues with calcification, focal ossification, aggregation of amorphous material containing cholesterol crystal and chronic inflammatory cells infiltration.
