An unusual case of chest pain and cardiomegaly.

Thymolipoma is an uncommon benign tumour of the anterior mediastinum, consisting of fat and thymic tissue. The diagnosis is easily missed because the tumour may simulate multiple intrathoracic pathological entities. It was first described by Lange in 1916, and since then about 50 cases have been reported. We describe a patient who presented with recurrent episodes of central chest pain and abnormal cardiac silhouette due to a thymolipoma.
